I don't understand why you would include them, as its not necessary. Are you applying for a field that requires a separate application which doesn't include an actual copy of the scores from the NBME? I'm not sure why you are sending out CVs.
When you apply for residency you generally (almost all fields use ERAS now) apply on-line, creating an on-line quasi-CV and your scores are provided to the programs.
I suppose if you wanted to highlight them, you could, but I think the examples you've seen were for people applying before the days of ERAS or other methods of electronically transmitting your scores.
Believe me, residency programs will download your scores, put them into their algorithm and make a decision about whether to invite you for an interview, without having to restate them on a separate CV (most programs will not take extra documentation outside of ERAS anyway). Once you've reached the interview stage, your scores generally don't make much of a difference as its already been determined that you meet the minimum criteria.
Just my two cents...
