I like that question.

A relation is a set of unsorted, unordered unique tuples, which may only contain data - not text. I'm not sure about the last bit.

But which leads back to the question. If a sort column/attribute is included, is it definitionally destroyed by saying it doesn't sort, or that whatever is sorted is not a, relation? Is it just semantics, as the term is commonly used? If you have horses at the gate, in other words, and their performance is tied, among other factors, to their start position, then is that not an ordered relation?
