I'm only another undergrad so take my advice for what its worth, but currently his chances are pretty much zero for MD in the US. The MCAT score cutoffs vary between schools, but I'm guessing he's below all of them. There might be schools that don't autoscreen, I don't know , but unless he's got some CRAZY AWESOME Ec's or life story, he doesn't stand a chance there either.
He might be able to get an acceptance in the carribean, I don't know, but make sure he does his research before applying there. Look around SDN and you'll see all the flame wars debating Carribean MD schools. Pretty much all credible sources on SDN mutually agree Carribean is a horrible idea though.
If you make this post in the "What are my chances?" area in the pre-allo forums you'll get more responses from much better sources than me.
