I just did some testing. What version of tla are you using? Because 
tla-1.3rc3 will let you register an archive with an incorrect name, but 
when you try to "tla get" it warns you that the name you are using is 
incorrect.

So, I am changing a little of what I said. In general, this bug has been 
addressed. (Maybe not 100%, but you can't 'get' a tree with the wrong 
name anymore.)
