Rules doesn't load rules.inc files as expected [#1452540]

I have a custom module with following helper function:

/**
* Implements hook_rules_action_info().
*/
function userpoints_rules_mcs_rules_action_info() {
  ...
  $actions['userpoints_rules_mcs_action_txn_list'] = array(
    'label' => t('Load transactions'),
    'named parameter' => TRUE,
    'parameter' => array(
    ...
      'tid' => array(
        'label' => t('!Points category', userpoints_translation()),
        'type' => 'integer',
        'options list' => 'userpoints_rules_get_categories',
  	'optional' => TRUE,
      )
    ... 
    ),
  ...
  );
  ...
  return $actions;
}

something is not write because I get the followin error from time to time:
PHP Fatal error: Call to undefined function userpoints_rules_get_categories() in /[drupal_path]/modules/rules/ui/ui.data.inc on line 99, referer: http://localhost/admin/config/workflow/rules/components/manage/rules_order_points_moderation/add/2/action

function userpoints_rules_get_categories() is defined in module userpoints_rules.rules.inc so even by name should been loaded previously. I don't exactly understand how rules.inc files are included.

Please help.

Hmmm... And the same script is working fine right after clear cache for one time, then that error apears... I think the problem comes from way Rules is setting its cache or something...

EDIT 1: If I make a custom function callback instead of 'userpoints_rules_get_categories' something like:

function userpoints_rules_mcs_get_categories() {
  if(!function_exists('userpoints_rules_get_categories')) {
    module_load_include('rules.inc', 'userpoints_rules', $name = NULL);
  }
  return userpoints_rules_get_categories();
}

is working fine only if I put it in .module not in rules.inc file. I don't understand...

Edit 2:
NO IT IS NOT WORKING IN EDIT 1
The error is in fact from an alteration in hook_rules_action_info_alter, I have a line like this:

$actions['userpoints_action_grant_points']['parameter']['moderate']['options list'] = 'userpoints_rules_mcs_moderate';

The error function is 'userpoints_rules_mcs_moderate' wich is defined in userpoints_rules_mcs.rules.inc file that is not included when the hook_rules_action_info_alter() is called from userpoints_rules.rules.inc, the one that provides $actions['userpoints_action_grant_points']. How the hook_rules_action_info_alter() works?
Can we change 'option list' callback function of other module with this hook?
Why our hook_rules_action_info_alter() rules.inc file is not included by rules when an action is altered via this hook?
Is this a bug or there is another way to implement it?

Thank you very much for your time!

Did you use an example from Rules tutorial as a base for your implementation?
I've spent about an hour trying to solve exactly the same issue.
Finally I've discovered that 'module' parameter is misconfigured: there should be machine name (or no at all), not user-friendly.
