IDATERMS

Have you tried to find out which one from your tags was created first.
The problem is that there is no record of the publish date on the wp terms from WP Database.
So I added extra with ID term to your taxonomies ..
By default Tags and Categories pages will have the column.
If you want to add ID Date column to your custom taxonomies go to the plugin settings page at Settings -> IDATERMS...
Settings page to choose on which taxonomy you want to show ID Date column.
Ex If your site has many tags and you want to find out.
If you need to know ID of any term quick and easy...
