[flexcoders] My column doesn't sort correctly in Flex 3 Beta 2

[Nate Pearson]

My column used to sort correctly, IE:
28,000,000
16,000,000
6,000,000
4,000,000

Now in Beta 2 with no code changes I get:
16,000,000
28,000,000
4,000,000
6,000,000

What gives?  Is it sorting it alphabetically?  If so how do I change
it back to the way it was?

Thanks,

Nate
