wait, are you just trying to import a sales order with pricing?  not "updating" a sales order??? because thats simple.  You just need to ensure you upload and have the PRIUNITPRC column on there and populated with whatever you want it to price at.  You can't update existing orders this way, but you can totally import a new one.

I think everyone is assuming you are trying to UPDATE an existing order, but after reading again, maybe you just want to import with set pricing?
