If you use 'mv_price' instead of 'price' in your cart attributes, the 
subtotal should tally up automatically in the foundation demo, since the 
CommonAdjust atom '$' is designed to do this.\

Do you really need to post the taxrate individually with each item? Do your 
taxrates vary per-item and per-order? If not (or even if so), you should 
just use one of the built-in methods for calculating tax that are available 
in interchange. If you really need to do it your way, I guess you could do 
something like this in Perl:

my $tax;
foreach (@$Items) {
        $tax += $_->{mv_price} * $_->{quantity} * $_->{taxrate};
}
$Tag->assign( { salestax => $tax } );
