Order with another orders_status

[marklask]

Hello,
I would like to do a change in my virtuemart 2.0.6 i Joomla 2.5.4
Standard orders is writing to mysql with order_status "P" - pending.
But when product stock is 0 (and low) I would like to order with another order_status - with "R" - reservation.
Where I should change it? Where I could find a "query" which writes orders with status "P" ?
best regards

I would just like to know how to have an email sent "Confirmed". Now it always sends "Pending". If you are checking out with PayPal and the order goes through it should be sent confirmed anyway. The customer gets confused when he sees pending with this message," Reason:The payment is pending because it was made to an email address that is not yet registered or confirmed." I now it would upset me.
