Fix needed

I am hoping someone familiar with that part of the core will volunteer.
I have created a table column price_US in products and variants table.
With the below code in catalog.cfg, the alternate price is used.  However
when adding products w matrix options to the cart, the default price is
used.
thank you,
tom friedel


Autoload <<EOR
[perl arg="scratch config"]

$Config->{Options_repository}{Matrix}{map}{price} = 'price_US';
$Config->{PriceField} = 'price_US';

[/perl]
