How Do I Get My Post Tags to Alphabetize?

Question

I'm using a self-hosted WordPress site with a Child Theme of Twenty Thirteen. After I requested the same question in the above title, the Child Theme's Developer suggested that I come here and attempt to create a new plugin to accomplish my goal.

Isn't there an easier way to simply Copy & Paste some altered code from the Parent Theme into the Child Theme instead of creating or using a current plugin?

Here's a link to my Child Theme's homepage which uses a Masonry Layout: https://shapeshifter3.com/

You could use the filter term_links-post_tag to sort tags while ignoring their case:

add_filter( "term_links-post_tag", 'themeslug_sort_tags_alphabetically' );

function themeslug_sort_tags_alphabetically( $tags ){
    natcasesort( $tags );
    return $tags;
}

This code is to be placed in the functions.php of the child theme.
