I think the simpler answer here is that your ISP is blocking all external requests for open ports ... I know my ISP does that.
If that was true, grc.com would show the port stealthed.
More to the point, if that were the case you wouldn't be able to use the internet at all. All that script does is initiate a connection to the IP address, exactly how your browser would if you tried to visit a website.
Not really: the stealthing is done on incoming traffic. Outgoing traffic is unfiltered, and replies to that are allowed through, as the local port is often well into the client port range. I usually see port numbers of 3000 or more.
