Special piano designed for religious sort (12)

I believe the answer is:

episcopalian

'religious sort' is the definition.
(someone who belongs to an episcopal church)

'special piano designed' is the wordplay.
'designed' indicates anagramming the letters (designed with the letters).
'special'+'piano'='specialpiano'
'specialpiano' with letters rearranged gives 'EPISCOPALIAN'.

'for' acts as a link.

(Another definition for episcopalian that I've seen is " Member of a certain church".)

I've seen this clue in The Times.
