Maybe...
AND (table1.field1 > table1.field2 )=.t.

...since you have an index on that expression, it should constitute a side of a relation expression, as the book says. I know this sounds silly, like most of the other things I'm writing today (west wind? sun spots? I'm under influence of myself? Who knows.), but shouldn't take long to try.
