As John says, the spoor extension is pretty easy to work with. It supports SCORM 1.2 'out of the box'; if you need to use SCORM 2004 then you do need to do a bit of manual work - see the documentation for the _scormVersion
setting in the README.
For my sins, I'm kind of the SCORM expert on the project so feel free to send any questions you have my way and I'll answer when I have a spare moment (hah!)
xAPI, on the other hand, is very much a 'work in progress' - I'm not sure how well it works with the Adapt Authoring Tool (Builder)... but if you're working with the Framework it should be usable but will take a fair bit more fiddling I should think. We've certainly done a couple of projects with it. There's a chat room dedicated to it here.
