I stand corrected. (I should have checked DerivedAge.txt.)
In another message Ken wrote (in a chapter of "Every character has
a histroy" ;-):

Perhaps not a mistake, but part of the oversight. Now that mirroring
cannot be changed, and the use for ORNATE parentheses is mostly in
RTL contexts, it would be more logical to swap these properties (and
properties that depend on the Ps/Pe values). In addition to adding a
note (in NamesList.txt) that these characters are intended for use
in RTL contexts. Anomalies resulting from using these in LTR contexts
would then have to be dealt with by other means (by someone editing
the text), if needed; rather than having to deal with those anomalies
in the expectedly more common case of RTL usage (which I venture to
guess isn't actually done).
Ever trying to fix things...
