I'm having the same problems with your library that also affects this one too. I can set the brightness, the script closes, and then 30 seconds later the OS resets the brightness back to the level it was before the script ran.
I have disabled the "Automatically adjust brightness" setting in the OSX control panel, and I don't know why else this would be occurring.
