Odd results

Hi - I was testing some IP addresses the other day that I knew shouldn't be accessible and although valid addresses, are probably not routable (certainly ping fails and traceroute shows them to be unreachable occasionally or just times out) I ran a UDP scan using -sU -O -v -v -P0 - this took over a day to complete - but finally came back with a whole bunch of open ports - between about 10 and 25 (I tested 3 separate IP addresses) - apparently a random spread. I'm pretty sure the results are anomalous - as I know exactly what services are actually running on these IP addresses - and it isn't any of the ones the UDP scan returned. Also - a scan using -sS against the same IP address finishes in a few minutes and reports all ports as filtered. I was just wondering why I got the open ports with the UDP scan?
