IFLDA   IFLDB
1    +      1      = 2
1    +      2      = 3
2    +      1      = 3
1    +      3      = 4
2    +      2      = 4
The result looks ascending to me. I guess you really meant to concatenate (string version of) the values, and not just sum them. Try using:
Index on Transform( iFldA ) + Transform( iFldB ) Tag XFLDAB
censored.
