Hi inittowinit --
The GMAT score is pretty important at all schools. That's because it is a reliable indicator of how someone will do in the rigorous curriculum at those top programs. Believe us when we say it, bschool is *hard*!! Success on the GMAT is strongly correlated with success in the quant-focused subjects in a MBA program.
That being said, the schools look at EVERYTHING - we even did a post on this recently:

If you have an especially interesting profile, then it's possible for the adcom to take interest in you even if the GMAT is lower than average. We see this a lot, and it does happen. We suspect that some schools including Stanford look particularly closely at the lower-scoring candidates to see if they are that special case. Of course, the average GMAT score at Stanford is ridiculously high, so obviously most of the lower-scoring applicants do not make it in. But Stanford and many other schools are open to it - they absolutely look at every single application, they do not simply filter on GMAT score and skip the lower-scoring candidates.
Unfortunately, there is a very common phenomenon among candidates, to think that maybe they will be the exception to the rules... If the profile is mediocre or exceptionally average, then a low GMAT is going to be the kiss of death at a top program. Hate to say it, but it's true.
Not sure if this helps, but that's our take.
