testing for randomness in sample of ints

I have a big array of integers that goes from 1-99, and im trying to determin if the are in a random order / the distripution among them is random.

i implemented the runs test. http://ift.tt/2kUCdk1

i also checked the avarage repetitions per numbers. And checked percentage above/below the avarage for each number. (fx: 5 been picked 104% more then the avarage number)

i looked into die hard test http://ift.tt/1dmmJNh but could only find relevant info / examples / tutorials on 'the runs test'

Any idea for further tests i can implement to determin randomness among a colletion of random numbers ?
