Collects the rags after sorting (7)

Ross

I believe the answer is:

gathers

'collects' is the definition.
('gather' can be a synonym of 'collect')

'the rags after sorting' is the wordplay.
'after sorting' indicates anagramming the letters (I've seen this in other clues).
'the'+'rags'='therags'
'therags' is an anagram of 'GATHERS'.

(Other definitions for gathers that I've seen before include "Infers" , "Assembles" , "Understands" , "Harvests" , "Gleans" .)

I've seen this clue in The Telegraph.
