The same for strings, where mere binary (case sensitive) equality often 
is useless.

Furthermore Pascal 'case' supports ranges, which deserve a stricter 
order than only equality. Then the sort order of strings also depends on 
the encoding (codepage, MBCS, UTF...).

And last not least strings IMO are complex types (array of char), as 
they have been in Wirth Pascal. The order of a comparison of ordinals is 
O(1), whereas string comparison is O(n).
