I'm using the underlying assessment package without the dotLRN Assessment Portlet, so I haven't seen the recent commits referred to here. However, I have submitted a patch to the assessment package that causes the points-per-section in the database to be updated every time a question is added or edited through the asm-admin UI. This fixed the problems I was seeing with a session's percent_score not getting updated correctly.

If you're not editing questions through the web interface provided by the assessment package, this patch won't help you. Perhaps someone could review the patch to see whether the same approach could also help in situations where questions are being imported.
