In the latest version the $ratings_options array is not being set correctly
before being passed to smarty.  Also setting parameter
ratingoptions='1,2,3,4,5,6' didn't work either. I suspect the
cgfb_comment_ops::text_to_options method isn't returning the right result.

In the smarty template:
   $rating_options:Array
(
    [1
2
3
4
5] => 1
2
3
4
5
)
1

Work around is to set
{$rating_options=['5'=>'5','4'=>'4','3'=>'3','2'=>'2','1'=>'1']} in the form
template
