High price often reveals excellence (10)
I believe the answer is:
perfection
'excellence' is the definition.
(thesaurus)
'high price often' is the wordplay.
'high' indicates an anagram (can mean drunk or on drugs and hence disordered).
'price'+'often'='priceoften'
'priceoften' with letters rearranged gives 'PERFECTION'.
'reveals' acts as a link.
(Other definitions for perfection that I've seen before include "Highest state" , "Faultlessness" .)
