Sorry, just my vague English - I was meaning to imply that the 
implementation itself was unhappy, rather than that there was any 
particular exteriour dissatisfaction with it :P
All the same, it could be more regular... the odd issue with the 
Reorderer is that its model contract is not quite so "clear" as that for 
some other components, since for example it is not perfectly clear how 
the implementor might want to represent the "value" of an individual 
element... and secondarily, whether we would want to support a "model 
modification contract" such that a successful modification at the model 
level would actually lead to the DOM elements swizzing round. That might 
be desirable from the consistency point of view but it is unclear 
whether the effort spent implementing it would be worthwhile.

Glad I could help,
