Queries :: Grouping Data By Week And Display

I am trying to create a query that will group my data by each week so I can sum up some numbers and display them on a per-week basis... Prefer the week to start on Sunday but really not picky about it.

Using the following in the query design window.

Week of Year: Format([Date],"ww")

This is returning:
1
10
11
12
2
3
4
and so on.. See the problem?

I tried sorting but that doesn't work.

I also tried the following:

Format([Date],"mmmm,ww")

But this is returning
December,51
December,52
February,8
February,9
January,1
January,2
January,3

Yes, there are some weeks without data but that's not the problem. The issue is that its putting February before January.. Why is this? Again, I tried sorting options and several other techniques but no success.
