Due to the new functionality mentioned here, you can now do this:

sub CheckGroupGlobal {
    my $client = plugin::val('client');
    my $global = shift;
    my $value = shift;
    if ($client->GetGroup()) {
        for ($i = 0; $i < 6; $i++) {
            if ($client->GetGroup()->GetMember($i) && $client->GetGroup()->GetMember($i)->GetGlobal($global) != $value) {
                return 0;
            }
        }
    } else {
        if ($client->GetGlobal($global) != $value) {
            return 0;
        }
    }
    return 1;
}

sub SetGroupGlobal {
    my $client = plugin::val('client');
    my $global = shift;
    my $value = shift;
    my $options = shift;
    my $duration = shift;
    if ($client->GetGroup()) {
        for ($i = 0; $i < 6; $i++) {
            if ($client->GetGroup()->GetMember($i) && $client->GetGroup()->GetMember($i)->GetGlobal($global) != $value) {
                $client->GetGroup()->GetMember($i)->SetGlobal($global, $value, $options, $duration);
            }
        }
    } else {
        if ($client->GetGlobal($global) != $value) {
            $client->SetGlobal($global, $value, $options, $duration);
        }
    }
}

return 1;
