Fortunately for you there are 3 new schools (unfortunately for all current students and optometrists), so there will be more competition between the schools to fill their seats. With your numbers you could slip into one of the new programs I'm guessing. Established schools like PUCO and SCCO might be a long shot. I know PUCO, if they reject you, will tell you what about your application they didn't think was up to their standard. So if you are waiting to take another OAT when applications go out, apply to PUCO anyways, if your OAT was the hold up and you get a new better score before their seats are filled, you'll get in.
Another thing to consider- besides your collective OAT score, if any 1 portion is <300 many schools will reject on that alone.
Good luck to you
