Joe, the derivation of sak does not depend on order, as it is merely a part of an anagram involving another word.
Your clue, I thinks, digs a little too deep.
Using Kas, Turkey is calling up unusual geographic knowledge.
Compare another clue, in yesterday's Daily Telegraph (DT), in part: "In California."
The part answer was LA, which would be more in the nature of common knowledge.
However the whole word in the solution was Ladrone (I'll not explain the latter part), which is a word meaning a thief, not commonly used, nor found in all major dictionaries, which is annoying. It means a thief or highwayman, the word coming from the Spanish, apparently used only when referring to South America. While it is in the Chambers 20th Century dictionary (which many years ago was rated the best for DT crosswords), and is in the full Shorter Oxford (the two volume small print version) it is not in the large Collins.
EDIT>
Ladrone does appear in my 1967 Funk and Wagnalls dictionary which is to be expected as an American word. I believe the F & W dictionary is a major US source, or am I taking the wrong cue from the Rowan and Martin's Laugh-in Show - Very Interesting.
BTW, I have an application "The Sage" which has dictionary lists, anagrams, wild card, etc, etc. Runs in W10.
