When I install OOo, with the option for custom sort order, I also insert the
following lists: cardinal numbers; ordinal numbers in digits (including _2d_,
_2nd_, _3d_, & _3rd_ (in the U.S., the short ordinals are used by lawyers and
the long ordinals by most others)); and ordinal numbers in words (including
alternative capitalizations).

Rows might be labeled with numbers as words.

Alternatives do not interfere with sorting when the user types their preferred
forms into cells, as long as what they type coincide with what's in the list;
for example, One Two Four Five will sort properly despite the user not typing
Three; as a result, alternatives like 2d may be in the same list with primary
forms like 2nd.

Thirty is an arbitrary cutoff here.

The following 3 lists are here to support copy-and-paste into a patch:

I use OOo 3.0.0 OOO300m9 (Build 9358) with Fedora 10 Linux and don't plan to
upgrade now, since it's stable and upgrading takes time.

Thank you.
