Since I also have the latest version (as of yesterday) I ran your first
suggestion, Wolfgang and that compiles with the latest, but again in the
order Chapter 1, Chapter 2 etc. whereas I am trying to achieve something
that I admit is not usual, but the author is considering it for dramatic
effect. 11 Chapters (or parts) in all, starting with 10 and ending with
0. Of course I can achieve this in a very manual way, (and therefore
would have to do similarly with the TOC) but just hoped we might be able
to do it another way.

It is not compiling for me. The usual kind of error message
A number should have been here; I inserted '0'. (If you can't figure
out why I
needed to see a number, look up 'weird error' in the index to The
TeXbook.)
Try this version (which doesn't use the new brace method for registers).
%%%% begin example
\define[1]\ReverseChapterNumber
{\the\numexpr\somenamedheadnumber{chapter}{last}-\somenamedheadnumber{chapter}{current}\relax}
\setuphead
[chapter]
[numbercommand=\ReverseChapterNumber,conversion=A]
\starttext
\dorecurse{11}{\chapter{Chapter \VerboseNumber{#1}}}
\stoptext
%%%% end example
