GMAT 690 Quant (77%) Verbal (89%)

Hi Folks just looking for some advice. I just took the GMAT scored a 690 77% Math and 89% verbal. Was very disappointed as I was scoring between 690(first practice) and 740(2 days before the test) on the practice Couple of questions:

1) Do I need to retake the GMAT? I have heard schools look for at least 80th percentile in Math.
2) Do I have a competitive profile [b]for Fall 2007[/b] for HBS/Wharton/Kellogg?
