This is called Lexicographic ordering and based on what I gathered, it's handy when you are trying to make a dictionary aka alphabetical ordering for a set of characters etc.... I've seen a Harvard student use it to write a code for an AI to play Super Mario! and it also has several Wikipedia pages if you're interested to read more about it!
