OIC.

Incidentally, this is the first mention of "extension" in this thread. 
Writing an RT extension may be something that has been done dozens of 
times, but it's hard to guess that anyone in particular is doing it and 
asking questions about it on this list. You might get better guesses out 
of the rt-devel list. I'm not there.

That's an interesting fact that I'd somehow missed in 12 years of 
working with RT...

A Scrip references its Template by ID. Really. I'm looking at that in 
the database. It's also documented that way in the API docs, but looking 
further down I see hints of nefarious magic at RT::Template->Load() I 
also just tested and confirmed what you say: even if I specifically pick 
the Global:$Name Template in a Scrip, the $QueueName:$Name Template gets 
used. Spooky.

But Scrips cannot be that way: there is no RT::Scrip=>Name. There's a 
Description, but that would be analogous to a Template's Description. 
Since Scrips don't *HAVE* a Name, they can't override by Name, yes?

But I do concede that there's inconsistency. Thus is the world. 
Different things are different.
