Score and attempt CSVs may contain inconsistent scores #237

One case of this known at Newcastle: https://mas-numbas-lti.ncl.ac.uk/resource/5605

In tasks.py, attempt.raw_score (used in the attempts CSV) seems to be the reliable score. The % in the Attempts CSV and both the raw and % in the Scores CSV seem to depend on attempt.scaled_score which isn't apparently always the final attempt score.

This is the same issue as #289.
