Foul row (4)

I believe the answer is:

rank

I believe this clue is a double definition.

'foul' is the first definition.
(both can mean rotten)

'row' is the second definition.
(as in a taxi rank)

(Other definitions for rank that I've seen before include "degree" , "Relative status" , "Row - grade" , "Highly disagreeable" , "Downright" .)

I've seen this clue in The Times and The Guardian.
