The sort order depends on the vowel that precedes the length mark. For example, after the character ka, the - length mark indicates a long a and is treated the same as a, while after the character ki, the - length mark indicates a long i and is treated the same as i. Transliterating this to Latin characters, a sort might look like this. If canonical equivalence is applied in a particular linguistic sort, then canonically equivalent strings are treated as equal.
Oracle-defined linguistic sorts include the appropriate setting for the canonical equivalence flag.
