No, there's no reason for a source port to be a high number.  It'll just be
another DNS server doing a query, and being tricky by using 53 over again. 
Might even be considered a feature, if you've got a lot of outgoing UDP
connections - doesn't waste a port.  Not a particularly pressing
consideration, however.
