Thanks! I saw the note. uc_discounts is working for this site, but there were a few bug fixes, and modifications. I have tried to submit these items as patches as appropriate (in the issue queue, and in the long thread about discounts which seems to be mostly a struggle to find a maintainer at this point). Hopefully someone can pick it up, as I think this is definitely an important aspect to a lot of ecommerce-based sites. Once I'm able to get the userpoints doing what the client wishes, there will be some additional integration of userpoints and uc_discounts on my part.
