A better solution is to add the following to the preamble, and the you can use
scalebox as usual:

\makeatletter
\let\oGscale@start=\Gscale@start
\let\oGscale@end=\Gscale@end
\def\Gscale@start{\if@rl \oGscale@end\else \oGscale@start\fi}
\def\Gscale@end{\if@rl \oGscale@start\else \oGscale@end\fi}
\makeatother
