Hi Holly,
I don't think there are any scripts in the distribution that accomplish these things. I've ended up writing my own to do large-scale course creation and set assignment, but haven't gotten to the point of needing to also do set scoring. I'd be happy to share my script if you'd like to see it, though it would require some recoding in Perl to make it work in your environment.
