uri segments order

You could detect the parameter by the type

Code:

if(is_numeric($this->uri->segment(3)))
{
   $limit = $this->uri->segment(3);
}
else
{
   $orderby = $this->uri->segment(3);
}

Another way to go is to add the key in front of the value like a query string and use the $this->uri->uri_to_assoc(n) method.
