Shortcode not ranking negative votes

Hi Ricard,

Thanks so much for making a plugin that does what it says it will do! I have implemented it on a side project that collects stories from travellers, and lets readers rate them as “cool”(vote up) or “sad”(vote down).

The issue I am having is that I am unable to get the shortcode to display the negative rankings in order.

The “cool” stories displays fine. You can see it in the side bar widget:
[thumbs_rating_top type:"positive" posts_per_page:"5" order:"DESC"]

However, can’t get the shortcode to show the posts ranked by negative votes.
The shortcode I have used is this:
[thumbs_rating_top type:"negative" posts_per_page:"5" order:"DESC"]

This shortcode delivers the exact same results as the positive votes shortcode – even though the votes are different.

What am I missing?
