Passing actual score (points) to the LMS

As an aside . . .

LMS's and tools like Storyline have to follow the specs for the various standards (e.g, AICC, SCORM 1.2, SCORM 2004 3rd Edition, etc.).

If a particular data element is not defined to be sent and stored in the LMS then things get problematic.  Generally speaking, you want everyone to play by the rules.

When tools and LMS's start doing their own thing, interoperability gets tough to maintain.

But you might want to look at having custom variable information stored in the LMS.

How you then get that info to show in something like a LMS report becomes a big challenge.  Someone would have to know where the LMS is storing such info and if it can be displayed in a report.  LMS data schemes can get pretty complex so you probably need help from your LMS vendor, especially if your LMS is hosted.  And, all too often, having them do a custom report for this can be very expensive.
