Values that were set before the payment module and Scratch values that
were set inside the payment module are available at every step, so I
think the session is being maintained.

I did some digging into the code, and I found that in route_order in
Order.pm, and I see near the beginning:
my $value_save = { %{$::Values} };

And then near the end of the function:
$Vend::Interpolate::Values = $::Values = $value_save;

So, am I right in thinking that saving data to the values space in an
order route won't work for me?  I assume that I will have to put my
payment processing outside of the order route:
[charge route="mypaymentroute"]
and then submit the order after that.
