I think it comes down to that being "selective" does not necessarily only mean GPA and MCAT. You have to consider your whole application.
I would say (from my experiences with advisors,fellow pre-meds, medical schools, and asking schools about my application and its weaknesses) that GPA and MCATs are "gateway" stats. Along with your PS and the short description of your activities (a.k.a. is this a real person?) they will get your foot in the door. MCAT and GPA in the right range will get you in the "we'll look at your file again" pile. These "cutoffs" are different for different schools, if you have a 3.2 gpa, Hopkins is more likely to toss your file than, lets say, your state school with lower mean gpa's and mcat's.
But to get accepted at most medical schools (if not all) you have to demonstrate to them that you are more than numbers, you have to convince them that you are a human being with a passion for helping others.
I've seen people get rejected (post-interview) with gpa's of 3.9 and 36 form schools such as Drexel and even DO schools. And I have seen people with low stats get into schools that are "out of their league".
It comes down to being well rounded...have a solid base with your MCAT and GPA, mix it with real medical experience, slap some research on top, squeeze some community service on the side, finish it off by sprinkling a little human compassion on top and you'll be a sure bet at one of your top-choice schools.
Oh, and apply broadly...that always helps...
