I wrote an AppleScript droplet that appends its own name as an OpenMeta tag/tag bundle (yes, you can have multiple comma-separated tags), and just updated it with the new OpenMeta so it mirrors 10.9.x tags. This way you don't have to use Folder Actions (which means you don't have to have a folder and therefore that you aren't moving files, just applying tags).

(please feel free to fork and fix; my code is surely atrocious)
Talking of meta. Ought there be a way to actually find out which repetitive action that we can create a shortcut for, we are wasting our energies on? Sme sort of self spy that tells us, hey look, automate this instead. Because that would solve the problem of having all the keyboard used up in shortcuts.
Thanks for the tip though.
