That is not possible (in the general case and the one you are interested 
in) because the standard required SHA-1 to be accepted.

But, of course, you are not required to use the exit code for a 
decision. Run

gpg -v --status-fd 1 --verify

and check the output for a line starting with "[GNUPG:] VALIDSIG". It if 
appears then the seventh field after VALIDSIG is the digest algo number. 
Check that against your set.
