I get the same error.
I have the PAWN strings saved in notepad. If I copy and paste the strings out of Notepad and import them, they work fine. If I copy and paste the strings to these forums, it looks fine, but it fails to import. If I copy from the forums and paste into Notepad and then copy from notepad and import, it still fails.
I have no idea why. You can however, create a scale manually and insert the numbers as I have them listed.
