Have you tried to find out which one from your tags was created first? Or Which term for your custom taxonomy was last created?
Last one happens to me, I had so many terms on several custom taxonomies that I wanted to know which ones were last created. The problem is that there is no record of the publish date on the wp_terms table from the WP Database. But since IDs are auto-incremental we can use this field to order by date our terms.
So I added an extra sortable column with the ID term to your taxonomies (Tags, Catgeories or Custom Taxonomies).
By default Tags and Categories pages will have the extra column. If you want to add the extra ID / Date column to your custom taxonomies go to the plugin settings page at Settings -> IDATERMS.

IDATERMS

Add an extra column with the ID term to your taxonomies (Tags, Catgeories or Custom Taxonomies) so you can sort your terms by date.

This plugin is all about IDs and offers a twofold functionality.
a) Adds a custom admin options page with WP List Tables that allow you to get a delimited list of post/page IDs by taxonomy / tag or post type. Listing of IDs by template only works for pages, not posts.
This can be particularly useful when for example you are working with WP conditional tags, where it is common practice to create a delimited list of post or taxonomy IDs. If there are many posts or taxonomies required, the process of finding each ID one by one can get a bit annoying and time consuming.
This plugin makes it easier for you. It creates delimited lists of post/page IDs based on taxonomy/tag, post type, template or user selection from WP list-tables.
b) Adds a column displaying IDs in the posts/pages, media, taxonomies and users screens. It also offers the option to automatically copy the IDs of selected items.
For a clearer picture please have a look in the Screenshots section.
Features:
<ul>
<li>

<li>
Works fine with Woocommerce and WPML.
</li>
<li>
Provides a settings page to control functionality.

</ul>
Note: The “Copy Selected IDs” button added in the WP built-in post/page and taxonomy list edit screens uses Javascript and works for all major browsers (Note: IE 10+). The auto copy to clipboard function is not supported by Safari, but you still get the selected IDs in the textbox, so you can copy them manually.

ID Arrays

Get list of post IDs by taxonomy, post-type, template. Add ID column in posts, media, taxonomies, users screens with option to copy selected IDs.
