I believe the answer is:

peace

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

'order' is the definition.
(peace is a kind of order)

I can't explain the remainder of the clue.

(Other definitions for peace that I've seen before include "Quiet companion" , "[STILLNESS]" , "State of freedom from war" , "Accord" , "Absence of conflict" .)

I've seen this clue in the Irish Times.
