If you look carefully at the mapscript docs you'll notice that
'imagecolor' is of type colorObj instead of type integer.  This makes
things a bit confusing, but it's related to the way things work
internally in MapServer (parsing of the mapfile, etc.)... almost
everywhere in the mapscript colors are stored as a color index, the
imagecolor property is one of the very few exceptions that are stored as
a colorObj (R, G, B values).

So to set it you can use:

 $map->scalebar->imagecolor->setRGB( 255, 255, 255 );
