Well if you do ; 

print 0 + [10] ;

[download]
you will see that perl treats the reference to the anonymous array [10] as a number . So what you do is like : 
rand number

[download]

In my case this number is 27783332 and the array reference is 0x1a7f0a4 ( that you can see by doing print [10]) which is 27783332 in hex ...

If i repeat execution i get the same reference over and over again for this anon array. I don't know why but that's another problem ;)
