If you can form a half-cogent argument why USMLE scores should or should not be publicized, you can publish it in some crappy medical education journal and add it to your resume, like this gunner from Brown:

Also, this issue is becoming less contentious because USNWR is already reporting scores. You have to pay for their online compass subscription service. It's a step in the right direction until schools get caught fabricating their scores (as several undergrad schools have in the past), at which point there might be more impetus for the NBME to give the data straight from the source in order to restore dignity to medical education administrators. The next question is whether/when USNWR will integrate the scores into their rankings.
