Nothing? I just tried it and it seems to do what I thought it would.

(It suffers from not being as neato as Andy's Perl Golfy version  
though. -grin-)

j


$ cat j.pl
my @a = ("A", "B", "C");
for (1..50) {
   print "rand = ", $a[int rand(@a)], "\n";
}

$ perl j.pl | head
rand = A
rand = B
rand = A
rand = B
rand = C
rand = C
rand = C
rand = B
rand = B
rand = B
