The script is based on zenity, and because it does not provide a Question dialog with Yes and No buttons, the mapping is done in the message.
Well, here is my version of the script in Python and PyGTK to avoid zenity caveats.

import gtk
import gconf
q = gtk.MessageDialog(type=gtk.MESSAGE_QUESTION,
buttons=gtk.BUTTONS_YES_NO)
q.set_markup('Do you want to turn ON the AIGLX Service ?')
gconf.client_get_default().set_bool(
'/apps/metacity/general/compositing_manager',
(q.run() == gtk.RESPONSE_YES))
Save the script in the Nautilus script folder (~/.gnome2/nautilus-scripts) as AIGLX and change the permissions to make it executable by owner. Close Nautilus and right click the Desktop. You should now have a AIGLX menu option in Scripts.
Enjoy it.
