Dan Marsden posted an interesting history of SCORM development for Moodle including the difficulties of funding development and maintaining SCORM 1.2 compatibility through the years. SCORM 2004, now nearly a decade old, was never officially integrated and demand has lagged. According to the post,
Full support for SCORM 2004 is already available in Moodle by using the Rustici SCORM cloud plugin for Moodle and I think it is more cost-effective to purchase a subscription to their hosted solution which is much more stable/reliable and feature rich than what we could provide directly in Moodle anyway.
There is also a new version of SCORM (Tin Can) and I think it makes more sense to focus development effort on that rather than continuing effort to get an old standard working within Moodle that so far no-one has cared enough about to fund.

From Crowd Funding to Moodle’s Google Summer of Code the development ceases only as the options are exhausted. Luckily, as with all open source communities the code development need cease entirely as anyone in the community can take up the reigns and pursue complete development of 2004 in the future. However, with the importance of learning analytics and the sharing of granular information between systems becoming more and more valued in education, Tin Can API is a perhaps the best choice to pursue for future Moodle integration.
