A right row produced by order (7)
I believe the answer is:
arrange
'order' is the definition.
('arrange' can be a synonym of 'order')
'a right row produced by' is the wordplay.
'a right' becomes 'ar' (I've seen this in other clues).
'row' becomes 'range' (I've seen this before).
'produced by' is a charade indicator (letters next to each other).
'ar'+'range'='ARRANGE'
(Other definitions for arrange that I've seen before include "Place in order" , "Organise, plan" , "position" , "Marshal" , "Dispose" .)
