Random Numbers

I was thinking of some things to do for a mod and had an interesting idea. Would it be possible to have a value (eg. tinkers move speed) be randomly generated when someone created a match? For example, whenever someone started a game tinkers move speed would be randomized to some value and the game would start with tinker having that move speed. The end result would be tinker having a different move speed every time you start a new game. Would it be possible to do this through some sort of lua code or event? Thanks for the help :D
