Depends on the actual sort order (there are something like a dozen different sort orders; see the Config manual, section 'Sort Orders') and associated case sensitivity (hint: sorting and matching are 2 different things)
Your sp_helpsort output shows 'dictionary' sort and 'case sensitive', which from the Config manual says:
==============================
Dictionary order, case sensitive, accent sensitive
Case sensitive. Sorts each uppercase letter before its lowercase counterpart, including accented characters. Recognizes the various accented forms of a letter and sorts them after the associated unaccented letter.
==============================
So, from this definition yes, you would get the sort results you show, but this doesn't necessarily imply case insensitivity.
Case insensitivity would tell us that 'Ferrer' = 'fERRER' = 'FeRrEr' = ....
As for the manual comments about like operations being case sensitive ... *shrug* ... I've posted 2 examples showing all no's for case sensitive and all yes's for case insensitive ... so either the manual is wrong or the manual is incomplete ... but hey, it's Sybase documentation so wadaya expect!? ;-)
