Well, the kind of numbering can be really crucial. The *most*
important thing is in theory that the numbering (re)starts at the
point the author specifies. However, if a book has page 1 twice,
then it got a problem ...
If we look at law texts published on the web, they will usually (I
think) not rely on HTML or CSS list numbering, but rather type
them directly. Why? Because the numbering is crucial for the
identification of sections and law paragraphs. On cannot leave
this over to what possibly could go wrong in a UA.
But perhaps more important: When a web page relies on HTML or CSS
list numbers, the numbers typically disappaer if one copies and
paste them (e.g. into e-mail) Also, one cannot, in most UAs,
search for a HTML or CSS number either, regardless of whether one
use <ol type="some-list-style-type"> or ol{list-style-type:..}. A
law text that is impossible to navigate is useless.
So it is far from only a screen reader problem. It isn't even only
a CSS problem, since <ol type="some-value"> got the same problems.
