1. For the current post or inside a loop: [content field="tiny_embed" shortcode="true"] should work, please let me know if it doesn’t.
2. This could be possible with the [loop] shortcode – currently it can’t query custom taxonomies, but I plan to add this parameter soon. Do you mean: to pull all posts in the post type story, whose taxonomy storyline equals horror, then display a list of their tiny_embed fields? For example:
[loop type="story" taxonomy="storyline" value="horror"]
[content field="tiny_embed" shortcode="true"]
[/loop]
Not sure if I understood correctly about the child parameter.
3. This is also possible, if I add a new parameter (or two): order by numeric meta value. So, in the case of #2, what I imagine is like:
[loop type="story" taxonomy="storyline" value="horror" orderby="meta_value_num" field="serial_number"]
[content field="tiny_embed" shortcode="true"]
[/loop]
This would get all posts matching the query, then order them by the custom field serial_number.
For the “manual orderby”, do you mean you’d like to pull posts with specific custom field values, i.e., all posts with value 111, then 115, 118, 105..? Or, if you mean post IDs, I suppose you could individually list them like so:
[content id="111" field="tiny_embded"]
[content id="115" field="tiny_embded"]
[content id="118" field="tiny_embded"]
[content id="105" field="tiny_embded"]
...
Hmm, there must be an easier way.. One idea I had was: there is a plugin called Intuitive Custom Post Order, which lets you order posts by drag and drop, in the admin post list view. This way, you could visually order posts, then display the fields with orderby="menu_order".

I think with the addition of a few parameters, it’s totally possible to display the content how you want. Certainly pushing the limits of this plugin, but it’s a good chance to improve it, so I’m interested in making it work. 🙂
