Sorting NSStrings in NSTableColumn (need 10 after 9)

Hey all,
I'm having a problem sorting my NSTableColumn "properly".
It's filled with NSString objects which currently appear like so..

- 1
1
1/2
10
1A
2

However I need them to appear like so (the "proper" way)

- 1
1/2
1
1A
2
10

I'm tried searching the archives, docs, and google but I haven't found
anything on how to correct this. Sorting the "1/2" case isn't that big
of a deal, it can pretty much fall where it falls, but the "1A", and
"2" appearing after "10" is a killer for me.

Thanks,
Lee
