You are correct.  The software developer for Class Web explains this as

"The sorting sequence used by ClassWeb conforms to the Unicode standard
implemented by IBM in their International Components for Unicode (ICU)

library (the software used for character handling in ClassWeb). In
Scandinavian o (o with a slash) is not treated as the letter o with a 
diacritical slash mark but as a completely separate letter that sorts 
between the Latin letters o and p."

In Class Web's LCSH, the character ø ("slashed o" or "o with stroke,"
in Scandinavian languages) alphabetizes separately from a standard o
after z. For example, do a subject heading browse for the word
"sozusa," and
note the headings that come immediately after that one. In the printed
volumes of LCSH, headings beginning with "so" and "sø" are intermixed.
