On Unix this was traditionally done with a "pseudo-user" - a user
account that existed just for the program, e.g. "moo" in this case. It
would own the file, and the game would run setuid, which means that
regardless of who ran it, the program would run with the effective
user-id of "moo", and hence could read the score file.
