So the key is understanding how the escalation engine works, when it runs it runs as Internal Services an Admin account.
Now we know this we can limit the "Other" value to all those who are not administrators.
Try this and a constrain on the Cause Code pick list:
IncidentCauseCode not Equal to $(if CurrentUserRole() not in ("Admin") then "Other" else "")
