No longer called brother that's not working (3,2,5)

I believe the answer is:

out of order

I'm a little stuck... Click here to teach me more about this clue!

'not working' is the definition.
(I've seen this before)

I cannot understand how the rest of the clue works.

(Other definitions for out of order that I've seen before include "Not going" , "Ex-nun is" , "(Mechanism) broken" , "expelled from society" , "Unfrocked monk is" .)

I've seen this clue in The Guardian.
