I don't know offhand why it wouldn't work; quite a few standard menu 
items go to first responder actions defined on NSTextView.  Try 
investigating how everything is set up in your app; for example, take 
a look at your validation code, and see if that's being hit.

Incidentally, sorting of text lines is something that might 
reasonably be handled by a service, so that it would be available to 
all applications, rather than by custom application-specific code.
