The eplain.tex indexing macros + makeindex work well enough for
me to make money as an indexer :-) It may be possible to extract
them from plain.tex and input them into a Context run. (The entire
eplain.tex file has at least one incompatablity with Context, hence
I suggest a subset of it.)

In your case, instead of using e.g., \Category perhaps the indexing
could be wrapped up in a macro that put the value of \Category in the
indexing command. Can you use something like \the\Category?
Yes, an index is an index and a register is something that holds a
number, in my English at least. Perhaps Hans Hagen will accomodate
your request in the next update of his amazing manual. It is, after
all, much more readable even in translation than ``The TeXBook'' :-)
