AppleScript guardando variable global

Me gustaría acceder a las variables origTrack y origPlaylist desde otro AppleScript para poder volver a la pista y la lista de reproducción que se estaban reproduciendo antes de que se ejecutara el primer script.

Esto es lo que tengo en el primer script:

global origTrack
global origPlaylist

on run arguments
    if ((count of arguments) is 0) or (first item of arguments) is not "paused" then

        set origTrack to ""
        tell application "iTunes"
            if player state is playing then
                set origTrack to current track

            end if
        end tell

        set origPlaylist to ""
        tell application "iTunes"
            if player state is playing or player state is paused then
                set origPlaylist to current playlist
                set newPlaylist to playlist "Morning Mix"
                set view of front window to newPlaylist
            end if
        end tell
        tell application "iTunes" to play newPlaylist

    end if
    return arguments
end run

Segundo script:

on run
    set isPlaying to false

    tell application "iTunes"
        set isPlaying to player state is equal to playing
        pause
        set current track to origTrack
    end tell

    if isPlaying then
        return "playing"
    else
        return "paused"
    end if
end run
