Hi surfingjerry,
A 760/Q49 is an outstanding Score, so you can comfortably apply to any Business Schools that interest you. Many Schools do not care much (if at all) about an applicant's IR Score, so an IR6 (while a solid performance in that section) likely will not impact your applications - and most Schools are satisfied if you score at least a 4.0 (out of 6.0) on your AWA (which you have). IF you are curious about how an individual School/Program interprets either of those Scores, then you should contact them directly and ask (and each Schools Admissions Department will likely be happy to answer any questions that you might have).
In addition, since you are interested in some highly-competitive Schools, you would likely find it beneficial to speak with an Admissions Expert about your overall profile and plans. Those Experts should be able to answer your Admissions questions and help define the specific areas of your profile that could use some improvement. There's a Forum full of those Experts here:
