I'm to order skip (4)
I believe the answer is:
omit
'skip' is the definition.
(I've seen this before)
'i'm to order' is the wordplay.
'order' is an anagram indicator.
'im'+'to'='imto'
'imto' is an anagram of 'OMIT'.
(Other definitions for omit that I've seen before include "Leave something out" , "Exclude; forget to include" , "Exclude; veto" , "Leave out or fail to do" , "Skip" .)
