I just watched the Spock's funeral footage on DVD. If you freeze-frame during the lowering of the coffin into the torpedo tube, you can see that Captain Scott is wearing the same black trousers as everyone else, though he does have his bagpipes.

The only other place I can think of where they wore dress uniforms in the movies is in Undiscovered Country, when they have the dinner with the Klingon envoys. Unfortunately, I don't have that one on DVD (I know, bad Trekie), so I can't verify it.

If I were going to make a Montgomery Scott costume, I'd use the B&W Scott, as that was definately seen onscreen during the TV series, even if I were going to use a movie-era tunic.
