Dear Vlad,
Ordering claims on a page as you suggest would not work well, since
several other orders must take precedence over the order you suggest.
First of all, statements are grouped by property and you don't want to
change this. Hence, you cannot use the order across statements of
different properties, since this would force you in some cases to
ungroup (which would have other disadvantages).
Second, it makes sense to order statements of one property by other
aspects, e.g., by time, to make it possible for humans to find
something. Hence, again, we are not free to use the order to encode
further information.
So what remains is to order quantifiers inside statements, but there it
is rarely relevant (usually there are only a few qualifiers and all of
them can be seen at once, without getting tired).
In summary, order does not lend itself as a way to encode much
additional information, since there are usability concerns that make you
want to change order in different contexts (or maybe for different
users), since order cannot be preserved when remixing data, and since it
is overall too implicit for people to build up a shared understanding of
what it is supposed to mean (you don't want fights about whether some
item has to be in fourth or fifth position of some list based on some
vague understanding of "quality" or "trustworthiness" -- it would be
very hard to find objective arguments for or against a particular order).
Cheers,
Markus

OK Lydia, what is the purpose of giving order of qualifiers then?
Along with helping to give a user a better representation of data, the order
can be useful in automated processing of properties. To my mind, it starts with
the most important entity data. Moreover, in case of contradiction, I would
assume that first properties are “ranked” higher. After all we are humans and
pay more attention to the top of page. Our mind may get bit tired by the end of
page. In an ideal world you are right that order does not matter, but in the
reality it may help algorithms.

Thanks for the link with sorted properties. Is this page updated
automatically or maintained manually by someone? In latter case this looks
weird to me, because the order may become not actual at some moment.
Yes it is maintained by hand by the editors.
It is curious that when properties are used as qualifiers we have a separate
field specifying the order (called ‘qualifiers-order’). Why not to add the
same at the top-level of entity definition?
It is just a heading to make the page more manageable - it doesn't
have a meaning beyond that.
