EMEDPA:
I'm a "non-traditional" student, 31 and a former musician. If I were you, I'd re-take the MCAT, as painful as that sounds.
Based on my personal experience (getting interviews), there doesn't seem to be a great deal of discrimination against older students. As a matter of fact, places like Case Western encourage older students to apply. So I wouldn't let the fear of being "too old" get in your way. As a matter of fact, you can use it to your advantage. Unlike a lot of applicants, who have little real-world experience, you probably have a lot of insight into the world that you should include on your applications. I know, without the experiences I had out of college, I would not have come to the decision to pursue medicine.
But again, I would probably take the MCAT over. Good luck!
