For the most part, residency rotations evals mean nothing. They're good for PDs to monitor a resident's progress. If s/he sees a bunch of bad evals, hopefully he can try to steer the resident in the right direction.
Having recently been in the job hunt, I have never had anyone request my file. It's possible that my chair and PD looked at the evals before writing my letters of rec, but I'm guessing they didn't.
Don't take your evals too seriously. I got so great evals from rotations I didn't put any effort into, and some terrible evals from people that just didn't like me. Now that I'm an attending, it all means didly squat.
