Steve,

An adder in shipping.asc is a good idea, but would require modification to 
every shipping method. You could build it into the handling system, and 
that would only have to be defined one time, but that's not something I 
would find desirable.

The way I've done this before is to use SpecialSub shipping_callout. This 
feature allows you to build a GlobalSub that takes the existing shipping 
amount, checks the cart for applicable items, then adds the fee. Whatever 
customizations you need will automatically apply to every shipping method. 
For example (untested):

# A perly true value in 'products.oversized' field adds UPS fee.
AutoModifier oversized

Variable UPS_OVERSIZED_FEE 25.00

Sub custom_shipping <<EOS
sub {
    my ($final, $mode, $opt, $o) = @_;
    
    $final += $Variable->{UPS_OVERSIZED_FEE}
        if grep {$_->{oversized}} @$Items;

    return $final;
}
EOS

SpecialSub shipping_callout custom_shipping
