Bush's SAT scores of 1206 don't make him a genius either. I had a friend who took the SATs on acid and got a 1500. That's a freaking genius (and in fact was one of the smarter kids of my graduating class - when he wasn't totally stoned).
That said, there's a lot of prep that can be done for an SAT score.
Looking at

Top two private Universities-
Harvard's SAT scores at the 50th percentile ranking
50th percentile for the SAT - Math scores: 690 - 790
50th percentile for the SAT - Verbal scores: 700 - 790
Yale- (Where Bush got in)
50th percentile for the SAT - Math scores: 680 - 760
50th percentile for the SAT - Verbal scores: 680 - 780
(Note based on these scores, it was more than SAT scores that got Bush into Yale)
