Hi, I've just done a bit of research around Wordpress integration.
I couldn't find any plug-ins, Learndash included, that actually support SCORM compliance.
They mostly require you to rebuild the course with Wordpress nodes as course components.
Learndash claims to support Captivate/Articulate because SWFs can be embedded into Wordpress posts but doesn't treat them as SCORM objects.
From this page:
https://www.learndash.com/pricing-and-purchase/
"Does LearnDash support SCORM? No, SCORM is not supported. LearnDash does support Tin Can API (also known as xAPI)."
There is a SCORM Wordpress plugin on Github that sort of works, but needs a bit of expertise to get working.

Hope this is helpful.
