in thread Pulling random elements from hash

Perlfunc / sort: The comparison function is required to behave. If it returns inconsistent results (sometimes saying $x[1] is less than $x[2] and sometimes saying the opposite, for example) the results are not well-defined.

I guess that means you don't really know what your code will give you. (Which kind of seems to be the point of it, but in another way. :))
