I was actually worried about the same things when i was preparing to take my GRE. I got a very good math score and, in my opinion, a bad verbal score. I got a 4.5 on the analytical portion.
Having said that, I believe PT schools do not put a lot of emphasis on the verbal portion. Being able to memorize words that aren't used in everyday conversation as well as connecting analogies doesnt really show how good of a PT you will be. On the other hand, a good math score shows you can think logically and solve problems, which correlates to good evaluations and creating proper plans of care.
In the end, I got into my first choice. I think the GRE is just one of many factors schools look at, but to answer your question, i think definetly make sure you get a better math score. Usually admitted students have a much better math score on average.
