You're pretty close:

        # Feed a copy of the message to 'foo'.  Failure of the program
        # isn't really an error, so use 'W' to suppress the "Program
        # failure" message while still capturing the exit status in $?
        :0 Wc
        | foo

        # save the status for testing.  Do *NOT* use EXITCODE as that
        # has special meaning to procmail.
        status = $?

        # test the status
        :0
        * status ?? ^^0^^
        action-on-success

        :0 E
        * status ?? ^^1^^
        action-on-status=1

        :0 E
        action-on-other-failure
