Cannot get limit to work - could be related to spaces?

[axelay]

Hi, I am trying to sort a list using the following:
$users = $this->redis->sort('users', array('by' => '*->time_created'), array('limit' => '0 2'));
But I always end up with FALSE, whereas
$users = $this->redis->sort('users', array('by' => '*->time_created'), array('get' => '*->username'));
works fine although it is not what I am looking for.

Am I doing something idiotic here or there is an issue?
For the time being I use:
$users = $this->redis->command("sort users by *->time_created limit 0 2");
but would be nice to have a limit filter that works :)

Keep up the good work!
