I'm trying to change the Rotation of the External Screen via Applescript, but I do not find out how to access this dropdown menu. Google seems to give me a lot about combo box and pop menu, but under Lion at least all this stuff doesn't work.

end tell
tell application "System Events" to tell process "System Preferences"
    tell pop up button 1 of tab group 1 of window 1
        click
        click menu item 3 of menu 1
    end tell
