My -transint- (a SSC package which is just a single help file) includes some discussion of transformations for percents and proportions.

I would guess that most of the percents in this case are between 0 and 100... but if there are some 0s, perhaps some of the methods developed by our friends who sort and count cells might help:
Bagwell, C.B. (2005). Hyperlog-a flexible log-like transform for negative, zero, and positive valued data. Cytometry Part A, 64(1), 34-42.http://www.cores.utah.edu/labs/flowcytometry/pdf/HyperLog.pdf

although I've never seen these used in regression in social science contexts. Anyway, thought this might be of interest.
