Garter is ordered and run to official (9)
I believe the answer is:
registrar
'to official' is the definition.
(registrar is a kind of official)
'garter is ordered and run' is the wordplay.
'ordered' indicates anagramming the letters.
'and' says to put letters next to each other.
'run' becomes 'r' (cricket abbreviation).
'garter'+'is'='garteris'
'garteris' is an anagram of 'registra'.
'registra'+'r'='REGISTRAR'
(Other definitions for registrar that I've seen before include "Official record keeper" , "Medic" , "Wedding recorder" , "University official" , "Official recorder" .)
