+- authorization and order_number (NEWLY DOCUMENTED IN 3.01):
+
+  Gateways will return one or two values from Authorization Only and
+  Normal Authorization transactions that must be submitted back with a
+  Post Authorization, Void, or Credit transaction.
+
+  If the gateway returns one value, return this as "authorization"
+
+  If the gateway returns two values, return one as "authorization" and the
+  other as "order_number".  Typically "authorization" is the more low-level
+  value returned from the underlying processing network while "order_number"
+  is a unique tranaction id generated by the gateway.
