What I did was create a shelf called "science-fiction". I put a mapping between "science-fiction" and a Calibre tag of "Science Fiction". I had the tags column set to "Tags". Then picking a book that I had previously linked to Goodreads, I added a "Science Fiction" tag to the book, and then performed the "Upload tags as shelves". I get a message in the status bar, and when I view the shelf the book is on the Science Fiction shelf. I just tried it all again now with a custom genre column and that worked fine too.
I did not see a status, but then to be honest, I didn't think to look for one, either. I did check the shelf (in my case it was Fantasy/Supernatural), however. I will try it again.
Stupid question: Do I also have to add the book to one of the exclusive shelves first, and then upload the tags or should it do it all at one?
