I think you should enter the score in whatever pitch is easiest. If  
your source score is transposed, then it's probably going to be easier  
to type it into a computer exactly as shown, transposed. If your  
source score is concert pitch, then it's going to be easier to type it  
into a computer in concert pitch. otherwise, you run the possibility  
of introducing errors into a score that will not easily be found.

\transpose a b

The easiest solution would probably just be to \transpose each part to  
what a modern orchestra uses, that's not uncommon to see a Clarinet in  
A part that's written in Bb for the sake of a modern orchestra where  
players may not have an A clarinet.


Just my thoughts.
