A number almost set right (6)

I believe the answer is:

adjust

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

'set right' is the definition.
(I've seen this in another clue)

'a number almost' is the wordplay.
'number' becomes 'D' (D is an example).
'almost' becomes 'just' (I can't justify this - if you can you should believe this answer much more).
'a'+'d'+'just'='ADJUST'

Can you help me to learn more?

(Other definitions for adjust that I've seen before include "carry out minor alterations" , "Adapt (to new situation)" , "suit" , "Adapt (oneself)" , "Fine-tune" .)

I've seen this clue in The Globe and Mail.
