Your solution for the problem is fine, I think. But I have two remarks on the code:
You check twice for the "1" at index 0.
Your loop is somewhat complicated. Try something like: 
my $index = 1;
foreach my $number (@numlist) {
    unless ($index == $number) {
      print "...";
      last;
    }
    $index ++;
}
