You're pretty late. Your chances will decrease notably, but I don't think you're screwed. Get that app in ASAP, and turn the secondaries around immediately. Many schools may not look at you until you have your pending MCAT score, but at least you'll have everything in. You'll be at a fairly severe disadvantage at the schools that shelve you until your next MCAT, unfortunately.
Your MCAT is not low enough to get you screened out immediately, so there isn't much reason to not apply now. Get it over with, and hope for the best.
