What happened?

I'm trying to modify the sorting of bibliographic entries in latex by appending SORTKEY as an extra field for the entries that I would like to manually sort (as per https://tex.stackexchange.com/questions/128387/sort-bibliography-with-same-author-and-same-year-biblatex). However it's not clear to me whether this is actually implemented at all in betterbibtex, since it is not included in the table of extra fields (https://retorque.re/zotero-better-bibtex/exporting/extra-fields/index.html). If it is a current feature, some clarification on how to implement this in practice would be really helpful.

Thank you.

It is not; there is no Zotero field that carries this meaning, and items in Zotero have no intrinsic order, so I have no information I could base this on.

since it is not included in the table of extra fields

which means it is not available this way, this list is exhaustive

If it is a current feature, some clarification on how to implement this in practice would be really helpful.

using the BBT-specific format, from the same page:

tex.sortkey: something

Thank you for pointing out the BBT-specific format. It is still not accomplishing what I need it to do, I suspect it may have to do with how this is outputting as an annotation, as per:

\field{annotation}{SORTKEY = \{b\}}

I'm still trying to figure out how it should be output and to modify my input string accordingly. I will post if/when I figure it out, for future reference.

The solution is to use = instead of :, as per the instructions under the BBT-specific heading on support page to generate "raw latex". Moreover, I used tex.SORTTITLE rather than tex.SORTKEY; the latter put the one labelled {a} at the top of the entire bibliography, whereas the former sorts only the items with the same authors and years.
