This bug has been fixed in the documentation's XML sources. Since the

Also consider its changelog:
4.1.0
A new sort algorithm was introduced. The cmp_function doesn't keep the
original order for elements comparing as equal.

Description:
------------
The usort docs tell us:
"Note: If two members compare as equal, their order in the sorted array
is undefined."
Other functions do not do that. The docs of every sorting function
should state if the function is sort-stable or not.
