Hi Tom,
[Bill, it looks like your problem is similar]
I think you're misreading the spec.
It says that if any per-key option is specified, then
that overrides all global ordering options for that key.
The following options shall override the default ordering rules.
When ordering options appear independent of any key field
specifications, the requested field ordering rules shall be applied
globally to all sort keys. When attached to a specific key (see -k),
the specified ordering options shall override all global ordering
options for that key.
[...descriptions of -d, -f, etc....]

Solaris8's /bin/sort behaves the same way GNU sort does in this respect:
# The `n' makes sort ignore the global `-r'.
$ printf '23\n2\n10\n'|/bin/sort -r -k 1,1n
2
10
23
# The `r' makes sort ignore the global `-n'.
$ printf '23\n2\n10\n'|/bin/sort -n -k 1,1r
23
2
10
$ printf '23\n2\n10\n'|/bin/sort -k 1,1nr
23
10
2
BTW, textutils-1.14 is almost six(!) years old.
Why on earth are you using (not to mention taking
the time to report bugs in) that version?
The latest is here:
