First of all, you should be proud of yourself for that great, oustanding score. Congrats!!
Regarding your query:
Your IR score is not problematic.
However, a 4 in AWA might raise concerns whether you wrote your essays and personal statements on your own (if they are really good, given the discrepancy to your low AWA score). So that could indeed raise a red flag, although you're verbal score is good enough to make the AdCom think that you were too exhausted or lazy to write a good essay rather than unable to do so. But still, it's possible that your AWA constitutes a problematic element within your application to Top Bus Schools.
So you
might want to retake your GMAT, but only if
a) you have enough time
b) you are
sure that you can achieve 760+ again -> most schools will consider the test with the best overall score, not the most recent, so in order to make that happen, you must score at least 760 again.
