Break down order for tin medals (9)
I believe the answer is:
dismantle
'break down' is the definition.
(I've seen this in another clue)
'order for tin medals' is the wordplay.
'order for' indicates an anagram.
'tin'+'medals'='tinmedals'
'tinmedals' is an anagram of 'DISMANTLE'.
(Other definitions for dismantle that I've seen before include "Unrig" , "To demolish" , "Take to bits" , "Strip down" , "Undo" .)
