How to log votes on the user that RECEIVES the vote

I created new rules for the votes in EasyDiscuss, so that when a user posts a question or reply, and this question/reply gets voted by other users, the author of the question/reply also gets points.

The implementation is something like this, the points are assigned OK:

DiscussHelper::getHelper( 'Points' )->assign( 'easydiscuss.someone.voted.my.reply' , $post->user_id );

Now I want to log this action in the authors history, I tried the following but it's not working:

DiscussHelper::getHelper( 'History' )->log( 'easydiscuss.someone.voted.my.reply' , $post->user_id , 'Someone voted up your reply to ' . $question->title , $post->id );

Please help me and let me know why the History helper is not logging the activity in the author that receives the vote.

Thanks

FYI the rule I uploaded looks like this:

<?xml version="1.0" encoding="utf-8"?>

<easydiscuss type="points">

	<command>easydiscuss.someone.voted.my.reply</command>

	<title>Someone voted my reply</title>

	<description>Add points for reply author when a user votes up on that reply.</description>

</easydiscuss>
