I got help with this. Rye in the #ubuntuone IRC channel discovered that this was indeed a new bug and will be fixed shortly in an update. There's a work around for now.
To "Unstick" music purchases:
1. Create an empty file called "placeholder" in ~/.ubuntuone/Purchased\ from\ Ubuntu\ One
2. Shut down syncdaemon with u1sdtool --quit;
3. Start syncdaemon with u1sdtool --connect ;
4. Wait for files to arrive
