No, I've banged my head some more, and that doesn't work. I think the issue is that if you call sh -e (sh -c, it seems to be actually), it runs and is evaluated, but then it doesn't have access to  %t or %<. I haven't seen anyway to substitute in the output of gpg-password & gpg-address & %t & %v into the final shell command.
