The “.words”-file is well formed Lua code, so you can just
integrate it as a table:

········································································
\define\wordcount{%%% Displays word count.
  This document consists of
  \startluacode
    local data = dofile"\jobname.words" %% Load data of _previous_ pass
    context(data.total)                 %% access the requested field
  \stopluacode
  \space
  words.%
}

\starttext
\setupspellchecking[state=start,method=2]
\ctxlua{languages.words.threshold=3}
\input knuth

\hairline

\wordcount %% call to the macro
\stoptext
········································································

Thanks as well, btw, I didn’t know the word count facility yet!
