Do you have good ECs otherwise? The way I have always looked at it (and I may have a different perspective due to my background I guess) is that when your application is in a sea of really high scoring applicants, sometimes its almost as if you will never stand out. Maybe being a DO is a harder battle also, but in my opinion if you did your homework and chose the places that are relatively DO friendly it won't matter much.
I mean, I have a Step 1-212 and Step 2-227 (I won't even mention my rank because it will make you sad for me) and I've gotten 3 ACGME interviews since it opened, plus 2 more from rotations. You can't always rely on scores. However, I am guessing that you have a solid application otherwise. Honestly, last year my boyfriend applied to EM with ridiculous scores (higher than or at least equal to yours), and he didn’t get many interviews until mid October. He ended up with 13 in the end. You're definitely not screwed yet.
