You can save the playlist file ( a file with .tsv file extension ) on the root directory of your USB drive. Then copy the .tsv file onto your PC / Mac and rename the file as a .csv file. Then you can use an editor or MS Excel to open and sort the .csv file, then save the sorted file as .csv file. Exit from the editor / MS Excel, and rename the .csv file to .tsv file.
Next time when you load the sorted .tsv file into your Genos Playlist, everything is sorted.
