Here, you need at least a pair of braces (actually, I'm surprised your code
doesn't give an error):
\setuphead [episode] [numberstyle=bold, textstyle=cap,
number=yes,before={\resetnumber[nuggetnumber]}]
It's better, however, not to use low-level commands, but context syntax:
\definelabel[nuggetnumber][headstyle=normal,way=bytext,prefix=no,text=]
\definehead [nugget] [section]
\setuphead [nugget] [number=yes,page=yes, before=\incrementnuggetnumber]
\definehead [episode] [title]
\setuphead [episode] [numberstyle=bold, textstyle=cap,
number=yes,before=\resetnuggetnumber]
context does all the housekeeping for you, no need to savevalue etc.

if you want a chain of commands, use a syntax like this:
\startsetups what:ever
\command 1
\command 2
...
\stopsetups
which you can then call with
\setuphead[argl][after=\setups{what:ever}]
