Use Internal Tag to Place Post at Top of Tag Page

Adding a featured post section to the of the index page was no problem. However, I am struggling to make past appear at the top of the tags page.

For example., at the URL below, I would like “Why Pseudocode” to appear above “Introduction Post 2” and, ideally, I could do this only within the “Introduction” section, perhaps using an internal tag.

Put differently: I would like post with an internal tag to appear at the the top of their tag page.

I’ve tried a few get and filtering techniques, but always ended up with the post on unintended pages or not appearing at the top.
