The variable MV_COUNTRY_FIELD specifies which form value to use for the tax
lookup and defaults to 'country'. Using something like the above code to
make sure your shipping value is set to the billing one if not set, you can
set the MV_COUNTRY_FIELD to your billing value name for the tax lookups in
the country table.

If you want to look into what's actually happening, its in Interpolate.pm in
the routine tax_vat().
