I don't see why putting a UserTag in CommonAdjust wouldn't work here.
You have all item attributes available in $item -- I have posted UserTag
access examples many times.

You can always set the mv_price attribute in the item:

[perl]
	foreach my $item (@$Items) {
		# All items are $5.00 in this store!
		$item->{mv_price} = 5;
	}
	return;
[/perl]

To use mv_price, you need to have an atom which is $ (or begins with $).

    CommonAdjust   $ ;pricing:price_group,q2,q5,q10:, ;:price, ==options

will work this way.  And of course it does work with all of the subtotals
and such, just as all standard methods do.
