graduate admissions - When applying for a phd, does a hiring committee cares about winning in various programming/data-mining contests?

When applying to a computer science PhD position in US, does it make sense to mention various significant achievements (finishing in top 5% percent) in programming/data-mining contests (topcoder, kaggle, hackerrank).

These competitions have their weight for tech giants, but does a PhD hiring committee takes them into consideration? If so, it would be nice to know how much weight do they have and what is the best way to present them?
