All I can suggest is the perl equivalent of the getNextSequence function

my $filter = {'_id' => 'userid'};
my $update = { '$inc' => { 'seq' => 1} };
my $col = $db->get_collection('counters');
$col->update($filter,$update);
my $id = $col->find_one($filter)->{'seq'};
print $id;

You can probably use find_one_and_update() but it didn't work on my old version 0.45 of MongoDB
