You can do this in Java if you want it to be "live"
You can also do it with PHP, but it'll require a page refresh every so often. Say if you refresh the page every 25 seconds, then it'll be close enough to "live".
You'd open up a connection to the web page and parse the result to look for the score. Unless they have something set up like a database you can read to get the scores.
Or you can have a cron job that runs every so many minutes to parse the pages and look for the scores, then saves them in a database. Then you're page just reads the results from the database. The user or script would have to refresh though, in order to see changes.
You can find out how to do all of this by searching through the forum, it's been discussed before.
