Here is (I think) the situation for random(3).

Lines will be (virtually) assigned numbers randomly; there are 27 possibilities.
There are 9 cases in which the first line is assigned a 1.  It is first in the 
sort.
There are 4 cases in which the first line is assigned a 2 and the other lines 
get 2 or 3.  It is first in the sort
There is one case in which all get a 3.  Again, the first line comes in first.

So, assuming my math is good, that means the first line comes in first 14 out 
of 27 times.  That is 52% and should match what people are getting empirically. 
 

This doesn't address broken random(), though.  It just emphasizes the 
importance of the big number for random().
