I think so many other things must matter in addition to the GRE scores, just as they do in admissions considerations. I attend a first tier grad school, it's one of the top in my field, and my GRE scores were quite low (combined 1230 V and Q, 5.0 analytical). However, due to my research experience, publications, conferences, overall academic record, and letters of rec, I was admitted into one of the top two awarded positions in my department and concentration. I also received quite nice offers from several other first tier schools. So, like admissions decisions, I really think that while GRE scores may be important to some GRFP reviewers, they may be just as equally unimportant to other reviewers if you have a strong record overall.
