You don't really have to do anything quite that sophisticated.  All you
have to do is make multiple connects to listening ports on them quickly.
Some sort of race condition.  If the port scanner you're using is remotely
efficient, up it goes.  I'm not surprised that they are vulnerable to more
complex attacks if their base IP stack can't even handle rapid-fire SYN
packets on different ports.
