T-SQL (SS2K8) :: Order By Numeric Doesn't Work

the select statement in the join orders the numbers asc and if you run everything below the case statement it works, but as you run the whole thing the order is no longer there.

I need the order to work. What am I missing?

Update tblObjectType3_14
Set [FldNumeric23764]= case when tID = 1 and Q.n <= 100 then 2
when tID = 2 and Q.n <= 150 then 2
when tID = 3 and Q.n <= 150 then 2
when tID = 4 and Q.n <= 130 then 2
