Is there any particular reason that you're not using the selectall_arrayref method? When I want an array of references to retrieved rows, I usually do it like this (untested):

my $tableref = $dbh->selectall_arrayref($statement);
# check for $DBI::errstr or whatever
my @ordered_questions = @{$tableref} if ref($tableref} eq 'ARRAY';

Of course, maybe you have your reasons. :)
