Tie::File (which is like your filehandle->array idea) could come in handy here, especially if you've got *lots* of questions :) 
use Tie::File;
use List::Util qw(shuffle);

tie @questions, 'Tie::File',"questions.txt" or die $!;
my @qnums = shuffle(0..$#questions);
foreach (@qnums) {
    print $questions[$_];
    # get answer & write to file etc.
}
