I want to throw in here that in general, the consensus in past discussions over the years has been that verbal is a better predictor for med school success in the first 2 years and on step 1. There are some conflicting reports, and some individual schools use various indicators for their own students as well though. But think about it this way, verbal it is essentially a timed reading comprehension test. Pull info out of a text and think about it critically in a short amount of time. In short, basically what you do the first couple years of med school. For the MCAT, it doesn't really matter what the passages are about, so much as you can skim it quickly, get the main points, and the be able to answer questions about it. These skills are important in step 1 as well. You will learn the basic bio and physical sciences that you need as you go, so you really only need a certain minimum competency in these subjects to be successfull. Advanced knowledge definitely helps of course, but you can manage.
OP: This all being said, don't let one low score beat you down too much. Schools can be very forgiving when looking at the whole applicant. I had very lopsided score as well, with a 6 point spread between my high and low sub scores. I am sure that it cost me some interviews, being so unbalanced. But it all worked out. A 6 in any section will hurt you, but you are not done. And with your high scores in the other sections, I am sure that you could re-test to bring verbal up if you had to. Good luck!
I don't really think it's appropriate to find correlation between a section and medical school success. Maybe for people who have taken it multiple times (multiple samples). One day, one test, one section, is too little to draw correlation.
