I have a second thought that addresses my concerns:

collection-fold[-keys]-left and collection-fold[-keys]-right are not
specified with regard to the order of enumeration.   For unordered
collections, collection-fold-right the implementation may either raise
an error or provide an enumeration in reverse order or collection-fold-left.

collection-fold[-keys]-increasing and collection-fold[-keys]-decreasing
are specified to be an ordered enumeration and are only defined for
ordered collections.
