Retrieve the most used post tags and display them in a ordered list

This function for wordpress will return a HTML ordered list (numbered), containing the top X most used post tags. This function accepts 2 parameters. The first one will be the amount of tags, and the second one could be set to false (boolean) when you don’t want to show the amount of posts where the tag has been tagged on. The second parameter is by default true (show the amount), which makes the parameter optional.
