R-bugs is the appropriate place to report this.
It may be particular to your system. Here's what happens on mine (Windows XP,
R 2.11.1)
> f <- factor(1:5)
> g <- reorder(f, rnorm(5))
> is.ordered(g)
[1] FALSE
> g
[1] 1 2 3 4 5
attr(,"scores")
1 2 3 4 5
-0.8120604 -0.0620255 -0.3724164 0.5652610 -0.3373658

All seems in order (so to speak).

Subject: [R] reorder always returns "ordered"
Or at least is seems that way to me. It's not a big problem, but the
behavior doesn't match the documentation. (I think r-help is the
place to report this. )
> x <- factor(1:5)
> x.ro <- reorder(x, rnorm(5))
> is.ordered(x.ro) # should be FALSE according to ?reorder
[1] TRUE
>
> x.ro <- reorder(x, rnorm(5), ordered=FALSE)
> is.ordered(x.ro) # should be FALSE
[1] TRUE
