Some problem I see:
My test for
sort("Only souls themselves and like of only understand themselves, As the souls understand themselves")
return correct string:
"and like of only souls souls the themselves themselves themselves understand understand Only As".
But after attempt I got:

Expected: 'and like of only souls souls the themselves themselves themselves understand understand Only As',
instead got:
'and like of only souls souls themselves the themselves themselves understand understand Only As'

Brilliantly!
