Using of st_tag_cloud(); and cloud_sort=name-asc doesn´t seem to work

Hi,
I use the current version of simple tags (2.3.2) and it seemed like the option of sorting the tags ascending by name doesn´t work. Or – well – it seemed like it was always random, whatever I choose in my call of st_tag_cloud.
My current call was the following:

<?php st_tag_cloud('size=true&larget=22&smallest=8&unit=pt&color=true&maxcolor=#000000&mincolor=#584126&number=70&format=flat&cloud_selection=count-desc&cloud_sort=name-asc&exclude=324,135,199,121&min_usage=2&notagtext=Keine passenden Stichworte gefunden&limit_days=31&title=<h2>Im letzten Monat häufig genutzt</h2>'); ?>

As you can see I have set it to “cloud_sort=name-asc” but each time I load my page the tags are displaying in an other order so it seems to be “random” (your default), but not like my chosen “name-asc”.

Greets, Stefan
