Calling taxonomy.selectNodes with no order argument (it's listed as optional) creates invalid SQL

The following URL produces an invalid SQL which is visible the next page refresh in the Drupal Admin interface: -

http://www.site.com/services/json?method=%22taxonomy.selectNodes%22&tids=1

The SQL that is produced for the above scenario is 'SELECT DISTINCT(n.nid), n.sticky, n.title, n.created FROM node n WHERE n.status = 1 ORDER BY LIMIT 10 OFFSET 0'. Notice the missing order field.

From what I can see, the default $order = 'n.sticky DESC, n.created DESC' in services/services/taxonomy_service/taxonomy_service.inc:taxonomy_service_select_nodes() is being overwritten with the empty order argument.

I have attached a patch that resolves this problem, not sure if it's the best approach.
