From your description, it sounds like you're talking about Georgetown's programs. From their CAM website, they have linkages with one DO; everything else is naturopathic, chiropractic, or IMG. While they show a list of (real) medical schools their students have attended, they don't say anything about matriculation rates.
The MS in Pharmacology doesn't give a lot of information about its program except the courses and job listings. This seems much less geared towards med school admission than the CAM program. This would be my last choice if I were you.
Even though it's too late for this year, you should check out the Georgetown SMP site. There is a huge amount of information regarding courses, medical school application help, etc. And they give stats about matriculation rates.
Anyway, if you just love the idea of CAM then I would go for it. I don't think it's the absolute best path that you could choose, but it doesn't look like it would hurt you as much as I thought. Plus if you love it, you might perform better than at a post-bacc program that you're less passionate about.
