I am looking for a word (which may not exist!). It means something like "relating to the order in which things are written down or expressed"; not, however, the the order in a dictionary (that would be "lexicographical") but rather the order in normal writing. 

So, if the word was "freddographical" I could talk about English and French being freddographically different because in English one says "blue car" but in French it is "auto bleu". Equally, in the UK we write a date 30/04/2011 but in the US they write 04/30/2011; I would call that a freddographical difference.
