I'll start by saying that I've never tried it before, but according to the 
docs, your shipping formula can contain any mixture of ITL and Interchange 
Perl objects as part of the expression, so this *should* work:

SHIP1   Shipping method 1       weight  0       9999    f if ( 
$Tag->subtotal({ noformat => 1}) + $Tag->salestax({ noformat => 1}) <= 28 ) 
{ #your shipping formula here }
