AppleScript: move a folder to library (to root) in iTunes Does anybody know how to move some folder to library playlist in iTunes?

I can move some folder to another folder using the following script:


tell application "iTunes"
    move folder playlist "3" to folder playlist "1"
end tell


The initial state is: 


1
|--2
   |--3


After executing the script state will be:


1
|--2
|--3


But I don't know how to move folder "3" on the same level as folder "1". Folder "1" is located in library. I mean the following structure:


1
|--2

3


You can see picture what I want to do using AppleScript
@ArtemG. then I assume that this operation could be done by editing the playlist file that is loaded by iTunes. It should  be located in ~/Music/iTunes/
