RST vs RST|ACK

Hi everyone A question on portscans.. I've been scanned for SubSeven a few times.. I set up a rule to track outgoing packets from the default port (27374) with the ACK flag set.. this caught 2 machines sending RST|ACK packets in response to a SYN... Can someone explain why these are sending RST|ACK instead of just a RST ? I thought RST was the standard response to a SYN from a closed port ? Is this because the initial incoming SYN had some data in it (I believe this is allowed...) I need to get an office copy of TCP/IP Illustrated :/ thanks !
