I can't speak specifically for gpgsm, as I only use GPG with OpenPGP
keys and not x.509 certs, but I would venture that the answer to your
question is "yes, gpgsm will select the correct private key for
signing" as that's standard behavior for such software.
Werner or others could answer authoritatively.
