Have never used that LMS, so I am just trying to offer you a possible solution which could work on older LMSs (since it only supports SCORM 1.2).
On video slides add a Next button at the end of the video to pause the slide at the end and force the user to click that button which will be visible only after having viewed the complete video. Go to the Reporting part in the Properties panel and set this button to be reported with a score. Do this for all slides. Now you can use the Quiz score as criterion for completion and require a passing percentage of 100%. You don't have to show the score to the learner.
