As has been pointed out, if you only need one derangement, it's better to simply shuffle the array (as you're doing - FY) and then simply rotate the copy.

We're building the house of the future together.

Without commenting on (or even understanding!) the rest of the code, my ears perked up on this:

/^"\s*(.*)\s*"\s*,\s*"\s*(.*@.*)\s*"\s*$/;
$nomes[$. - 1]=$1;
$mail[$. - 1]=$2;
$nomes[$. - 1]=~s/\\(.)/$1/g;

Never use $1 except in the context of knowing that you had a successful match. If the match fails, you'll get a stale $1, and that could ruin your day. In this case, if the match should never fail, add an "or die" to the match line.
