The random action isn't very useful imo. I expect rand(1,100) where the value returned is between 1 and 100, but in mightyscript, the function returns EITHER 1 OR 100. The only use for this is to randomize exactly two states (ie. 0 and 1; false and true). Not sure if this is your intended solution, but IMO, it needs to be implemented like a normal rand function in any other language.
