Quite honestly, no score is anything to be ashamed of. Yes, I'll admit to have been frustrated a few times, but you dust yourself off and march on ahead. I might suggest eliminating one's score altogether as a reason for wanting (or needing) comments.
Perhaps more constructive, and less inflammatory phrasing might be a good idea. Also, try looking at similar pieces or pieces in the same category that might've scored higher and see if you can be objective and find the differences yourself. Once you've done that, try simply asking for the opinions of others, and how they think your work could be improved.
