Here are the stats from GMAC (mba.com):
Scores for men/women by year
'00-01 541 men/503 women
'01-02 543/505
'02-03 545/504
'03-04 541/501
'04-05 541/500
Sure, this is just the average score, but we can assume that the score pools for each demographic are large enough, and the test is scored in a way that they will form a traditional bell curve. The bell curve for women will fall away 40 points earlier than for men.
Just so people don't miss the obvious, I will state it simply. A much higher percentage of men will have 700s and 730s and 760s and 780s than women. At the elite schools, a woman with a 670 would be about as competitive as a man with a 710. A woman with a 730 would be about as competitive as a man with a 770.
Here's a link to the GMAC report. Unfortunately, the section entitled "GMAT Candidates by Attending Institution, Sex and Testing Year" appears to have been redacted. That would have been exactly what we were looking for.

The overall testing pool is much weaker for men than for women; so the overall applicant pool will be weaker as well. To deny the difference in scores and the advantage of favored applicants is insulting to those that are from tough demographics, and especially insulting to those that are rejected in spite of better performance.
Regarding your assertion that women have better work experience; there is substantial evidence that because of family concerns (having children, etc.) women applicants, as a group, have weaker overall work experience than men. I will just say that this is the type of thing that is difficult to substantiate, but I think there's little to support your view and I don't buy it.
You may hate the assumption, and certainly you might be able to stand on your own merits, but the truth is that the application pool is weaker. My demographic is probably middle of the road for business school, but I certainly would not insult applicants from tougher demographics by suggesting that it is just as hard for me to get in. It's simply not true. Lots of women (just like lots of other under-represented minorities) would not get in if they were not from their given demographics. You may or may not be one of them, but don't exacerbate the plight of those that face tougher odds by denying the truth.
Here's some anecdotal evidence collected from admissions411.com - males/females with top scores at top schools (self-reported, not substantiated, etc.). Let's do R1 for this year:
Columbia ED:
0 female, 7 male, 9 are "private" and unknown
Chicago R1:
1 female, 13 male, 8 private
Cornell:
0 female, 7 male, 7 private
MIT:
1 female, 16 male, 28 private
Wharton:
1 female, 20 male, 33 private
Berkeley:
0 female, 9 male, 15 private
Kellogg:
0 female, 12 male, 26 private (surprising, I thought Kellogg would have a lot of high-scoring female applicants)
Harvard & Tuck: too many private (only 4 of top 25 scores at Harvard were not private)
So which demographic would you like to be competing in? Sure the numbers might just mean that men are more likely than women to visit admissions411.com, but there's a much more plausible explanation which is shown in the GMAC score reports.
I'll close with a quote from a
Manhattan GMAT article:
"Notice as well that the average GMAT score is appreciably higher for men than for women. This is great news for women with high GMAT scores, since they will stand out not only because they are women, but also because they are a coveted subgroup within a coveted subgroup. Of course, many other factors come into play in the admissions process (e.g., GPA, work experience, recommendations, etc.), but anything that draws positive attention to your application can only help your cause." The coveted subgroup is women - the subgroup within that subgroup is women with high scores.
