1.3 and 1.30 are different only in terms display and printing.  One 
approach can be wrapping your calls to the zsql in a python script that 
applies formatting before returning the relavent results.

res = yourZSQL(params or request is all set up)
return "$%.2f" % res[0].yourAmountThatYouNeedToFORMAT
