_features_sanitize returns different results on hybrid arrays

This is kind of similar to http://drupal.org/node/1089816.

On arrays that are part indexed and part associative, ksort is returning different values back, which is causing false overrides. I know these can be avoided but it would be nice if the Feature showed as DEFAULT.

Example (0 index is throwing ksort for a loop):

$a = array(
  'meta_name' => 'description',
  0 => 'meta_name',
  'test_key' => 'test_val'
);
ksort($a);
/*
Array
(
    [test_key] => test_val
    [0] => meta_name
    [meta_name] => description
)
*/

$b = array(
  0 => 'meta_name',
  'meta_name' => 'description',
  'test_key' => 'test_val'
);
ksort($b);
/*
Array
(
    [0] => meta_name
    [meta_name] => description
    [test_key] => test_val
)
*/

What do you think about adding a sort_flag, i.e.
864 ksort($array);
to
864 ksort($array, SORT_STRING);

This will alter how indexed arrays return back, i.e. 11 before 2, but that shouldn't be an issue as this is just trying to normalize 2 arrays for comparative purposes.

Thanks
