My goal is to create a new custom field (type String/Radio) with a newly created list of options. 

What I am able to do successfully via the API:
  - Create a the option list via the API using civicrm_api('OptionGroup', 'create', $params)
  - Create the new custom field of type "string/radio" via the API using civicrm_api('CustomField','Create', $params);   

What is not working in version 4.4.4 and 4.4.5 ( but did work in 4.3.8 )
  When I create the custom field, two of the parameters are:
           [options_per_line] => 1
           [option_group_id] => $tmp_option_group_id


The result in version 4.4.x is that the param 'option_group_id' is ignored, and the field gets associated with a auto-created option group with no option values. 

Any ideas on why the param 'option_group_id' is getting ignored in version 4.4.x when creating a custom field?
