Moodle mainly supports SCORM 1.2 which isn't really designed to report on a percentage of progress - just a final grade on completion of the activity. SCORM 2004 does have a "progress_measure" value that is designed to do this, but Moodle doesn't support SCORM 2004 (and doesn't provide reporting on that value) and AFAIK some of the popular SCORM authoring tools don't write anything to that SCORM 2004 value anyway.
This is all controlled using your SCORM authoring tool anyway - there's nothing we can really do about this in Moodle.
If you need to report on exactly where users have got to with incomplete learning packages you might need to look at something other than SCORM - maybe using the Moodle Lesson module with a custom report might work?
