Generally in computer science a function is a special type of subroutine that returns a values (as opposed to being called just for its side-effects). But in Perl (as the cookbook says) we don't make that distinction.

The two words mean the same thing. They're synonyms.

Course: Perlmonks.

Update: They are synonyms only because Perl returns last value of expression, evaluated in sub-block.
