In the source I'm looking at for useropen, I see:
case OREAD:
a = R_OK;
...
case OWRITE:
a = R_OK;
and subsequently
if(S_ISDIR(fid->st.st_mode)){
if(a != R_OK){
fprint(2, "attempt by %s to open dir %d\n", fid->u->name, omode);
*ep = Eperm;
return -1;
which seems to indicate that it's ok to open a directory for writing as well
as reading, which I took open(5) to say was not allowed. Could some kind
soul explain? Thanks.

That should be "a = W_OK;".

i'd say it's a mistake.
