Obviously, there's a lot of affirmative action in the med school racket: the acceptance rate (43%) for Mexican-Americans is virtually the same as for non-Hispanic Whites (44%) even though Mexican Americans average around the 26th percentile of the white distribution in MCATs and college GPA. And 36% of blacks get accepted compared to 44% of whites even though blacks scores and grades are down around the 17th percentile of the white distribution.
In fact, the AAMC posts offical grids showing how much easier it is to get into medical school for Non-Asian Minorities (NAMs) than for overall applicants. For example, 32.4% of "self-identified" NAMs get accepted to medical school with 3.00 to 3.19 GPAs and MCATs of 21-23, while only 13.4% of overall applicants get in with the same credentials. For applicants with 3.40 to 3.59 GPAs and 24-26 on the MCAT, 67.1 of NAMs get in versus 27.5% of the overall applicants (and somewhat less for Whites/Asians, of course).
In summary, it's probably a good idea to get a second opinion.
There just aren't many high-scoring NAMS. Only 45 of the 1,682 applicants who scored 39-45 on the MCAT (the highest bracket) were NAMs. In contrast, NAMs made up 1,731 of the 2,705 in the lowest scoring bracket of 5-14.
