It is simpler than many, but still unecessarily complicated, because of the amount of repeated code.

Presuming you want 3 each of the lowercase, uppercase, and digits, you can simplify the code to: 

my @ranges = ([a..z]) x 3, ([A..Z]) x 3, ([0..9]) x 3;
my $password;
while (@ranges) {
  $range = splice @ranges, rand @ranges, 1; # random pick
  $password .= $range->[rand @$range]; # random pick from the range
}

The whole thing of $password = join "", $password, ... in the original post is definitely worth unlearning if nothing else. {grin}
