I will second Necromonger's message. 67% will be a concern for the top schools (see the B-school application forum for an analysis I did breaking down percentiles of each section at Wharton). If you have other things in your background that can re-assure Adcoms that you are very capable with math, then it may be less of a problem.
I also agree that, if you are Indian, the group you are competing with has higher average scores at most of the top schools - and in particular higher Q scores. So, 710 is a very good score, but you'll need to consider some other factors before you know if it it's worth the effort to re-take.
