This isn't necessary. All you need is:

postinst: touch $SCORE; chown root.games $SCORE; chmod 0664 $SCORE

This works because if you change a package so a conffile does not exist in
the package anymore, dpkg leaves the conffile in place when you upgrade.

Note that you also need:

postrm (on purge only): rm -f $SCORE; (delete the directory tree $SCORE was in)

You have to delete the directory tree because dpkg has already tried and
failed to remove it by this point, and will not try again.
