Not sure, but it looks like the ICC has an api here.

Not sure if it is documented, but looks like you can kind of reverse it based on the query string parameters.

And it appears that the Indian Premier league has a jsonp based api.

This gets you the matches: http://datacdn.iplt20.com/dynamic/data/core/cricket/2012/ipl...

Then with the match id you can get the score. http://datacdn.iplt20.com/dynamic/data/core/cricket/2012/ipl... where ipl2016-01 is the match id.
