"Touch folders after opening" was already set, so that was no help, but Vero's suggestions were dead on, thanks so much!
I've removed alias as a file type. The Spotlight comment approach worked very well, and I think I'll leave those in, for those rare cases I accidentally launch Spotlight instead of Alfred with the wrong keystroke :-) The downside is that you see the real app name as the result (acgui not AccuRev), so there's a mental disconnect there before you go "yeah, that's the thing I really want to launch".
The workflow method is a bit more work, but is worth it because the presentation is much better. I've only used other people's workflows before, so that was new to me, but it was easy. Thanks again, I'm all set.
