Typically, MIDI devices don't send "Song Select" MIDI commands. That's a rarely used message to begin with, and it's usually something you would send to a device to get it to load something. Are you sure you are receiving a "Song Select" MIDI Message from your device? If you tap the bottom most icon on the right side of the list to bring up the MIDI listen dialog, then have your Roland send the messages, what do you see? Whatever it sends is what you should be triggering on to load the song.
