Just to be clear, a top GMAT score is better than a top GRE score. Why? Since the GMAT is the de facto MBA exam most admissions officers are more comfortable judging GMAT scores (and some have stated that they still prefer seeing GMAT scores). Not to mention that the GMAT is tougher than the GRE. But just to play devils advocate you could argue that schools might be willing to accept a lower GRE score because that score won't ding their prized GMAT averages. Though that doesn't excuse you from demonstrating a proven ability in Quant (this can arguably be done by taking a pre-MBA math course ).
