Yes you're right you could'nt get a TCL for cricket related. Anyway I am suggesting you something you want. Get a RSS TCL, which can read RSS feeds and show it on your channel, set the trigger to !score and use the following link for Feeds.

Ok first you asked me if it was possible to get Latest Scores of Cricket, I told you a nice a way and shared a proper TCL for that and it worked which is shown in your post.
For your 2nd question, which is Live ball-by-ball Cricket commentary erm.. well i can't help you with that either ask the person where you've seen that TCL or mIRC script.
