Here is something more complicated:

The first function (randl) generates a random number according to the logarithmic scale; it "favors" smaller numbers. The BiasedChooseFrom function picks an element; but it favors the smaller numbers. 
sub randl{
    return int( -$_[1] * log( $_[0] * rand() ) );
}

sub BiasedChooseFrom{
    return $_[ int( randl(4,int($#_/2)) ) ];
}
