[ic] Totals not correct

[Matt Kerner]

We're having two consistent problems with Interchange and the totals of 
orders.

1. The order total does not include shipping (it is calculated, but not 
added to the subtotal).
2. The order total includes shipping, but only the subtotal gets billed 
at the credit gateway.

I've been unable to find anything in the logs that would tell me what 
is causing this problem.  Does anybody have an idea?  This is very 
frustrating because it seems to happen on orders with expensive 
shipping.

Thanks,
Kerner
