That's true only in LC_COLLATE=C and a couple of other locales, certainly
not true for most other locales. Spaces/tabs and other non-alphanumeric
characters are often ignored for collation purposes, at least in the first
phase and they do make a difference only if strings without those characters
are identical. Similarly, digits may have smaller priority than alphabetic
characters etc., it all depends on your locale. Look at a vocabulary
for your specific language and see how things are sorted there.
If you want ASCII sorting, use
LC_ALL=C sort
