Unlucky to get a difficult script (4,5)
I believe the answer is:
hard lines
'unlucky' is the definition.
(both might be said to express sympathy)
'get a difficult script' is the wordplay.
'get' means one lot of letters go next to another.
'a difficult' becomes 'hard' (I've seen this before).
'script' becomes 'lines' (I've seen this in another clue).
'hard'+'lines' is 'HARD LINES'.
'to' acts as a link.
(Other definitions for hard lines that I've seen before include "Tough" , "Bad luck" , "Script full of tongue-twisters?" .)
