I don’t have a certain solution, but a few things I’d try to see if anything works better or exposes behaviour that explains this issue:
The log message sounds like the actively OS prevents any application except screen saver and the login window from coming to front at this moment. It sounds like it’s a bug that it works at all. What happens if you create another application (as a test, an AppleScript or Automator action should work) that waits for, say, 10 seconds, and then launches the app? If you turn on the screen saver and wait for that app to do the launch, does it work?
It could be that screensaver is run in a special way (e.g. outside the user’s login session) and therefore not permitted to launch other applications.
