If at least one person has taken an assessment and submitted it, but nobody has answered any of the assessment questions, then the questions' scores/comments in the Student Scores page can't be updated.
Steps to reproduce:
1) Create and publish an assessment.
2) Take the assessment as a student. Do not answer any questions - just click begin assessment and then submit for grading.
3) Log back in as the site maintainer and view the scores for the published assessment.
4) On the student scores page, adjust the scores/comments for an individual question and click Update. Your changes will be lost.
