What is wrong with the supplied:

        Order [order 
                code=the_sku
                form="
		    mv_cartname=[value merchant]
                "]the_sku</A>
 
I am pretty sure it is in 4.03, but can't be sure.

The one and true patch, by the way, which I would have put
in a flash, is:

	push (@parms, "mv_cartname=$opt->{cart}")
		if $opt->{cart};

Then you can just use a [order cart="[value merchant]" code="the_sku"]
You can even put this in catalog.cfg or interchange.cfg:

UserTag order attrAlias  merchant cart

Then it would be [order merchant="[value merchant]" code="the_sku"]

If despite this available mechanism you want to override the order tag
the way to do it is with a global UserTag, as that way your system won't
break when/if you update. If you want to override the entire routine
(in case it is used elsewhere) you can do:

GlobalSub <<EOR
sub total_junk {
    package Vend::Interpolate;
    sub tag_order {
	    your_patched_code();
    }
}
EOR
