Close, but you've confused the rule. DO applicants to ACGME programs must release their USMLE transcript, if they've taken a step. There is no rule that they must release COMLEX to ACGME programs. Many of the programs to which the OP is applying might require it, but there is no overarching rule about it2. IIRC (and aPD or others, please correct me if I'm wrong here), DOs applying to allo programs MUST release their COMLEX scores.
I guess taking Step 1, and doing well on it, would help. If you do poorly, not so much....3. You're actually probably going to be OK. Although board scores are used in all aspects of the interview/rank process, one of the major areas they're used is in the initial screen prior to deciding who to interview. So the fact that you've got so many interview offers already bodes well for you. Just release the COMLEX scores and be done with it, you have passing scores on both Levels. You should probably take USMLE Step 1, just to try to buff your stats. But be sure to hold off on releasing the score until you get to see it. A good score will help you, a crappy score or failure will definitely hurt you.
