The difference is in the term "sequence" which is not mentioned in (e.g.) R6RS 
numeric discussions.

I have done plenty of sorting, but have never used Scheme seriously for 
numeric sequences.  My usages are more typically something like:
  (if (< lo-bound x high-bound) ... )

I don't consider (low-bound x high-bound) to be a sequence (unless a sequence 
of lexical tokens--but that again is a different domain).

Yes.  This is a difference in perspective -- and usage.
