In a short subroutine, this:

@list = shuffle @list if $self->random_order;

does what's expected. Returns the shuffled list.
This:
use List::Util qw/shuffle/;
my @list = @{$self->answer_list_orig_order};
@list = shuffle @list if $self->random_order;
return \@list
returns the list unshuffled.
What's up with that?
So the difference is just the semicolon at the end? Works for me either way.
$ perl -Mstrict -wE 'sub foo { my $self = shift; use List::Util qw/shuffle/;
my @list = @{$self->answer_list_orig_order};
@list = shuffle @list if $self->random_order;
return \@list;} sub answer_list_orig_order { [1 .. 10] } sub
random_order { 1 } say for @{ main->foo }
