This was addressed in the data model for British Standard Draft for 
Development DD8723-5:2008, which is available at 
<http://schemas.bs8723.org/Model/Model.jpg>. This provided for concepts 
and arrays to have a notation that could be used to order them within an 
array. An array could also have a Boolean flag to indicate whether it 
was ordered or not, i.e. whether the order in which the entries were 
presented was significant.

The model has been refined for the forthcoming standard ISO25964 and I 
attach a copy of the current draft, which may be helpful for future 
developments. This also distinguishes between "Arrays" and 
"ConceptGroups", the latter including subsets such as subject groupings 
and microthesauri, which may be selected and ordered on a different 
basis, independent of the hierarchical relationships between concepts. 
As I understand it, at present SKOS does not make this distinction but 
has to use what it calls "collections" to represent both these elements, 
making it difficult to deal with them properly.
