This was surprisingly difficult. (And I could not make it work in in JS :-() Assuming every chapter starts on a new page with a paragraph style called "Chapter" you can do something like this:

tell application "Adobe InDesign CS3"
  tell document 1
    try
      delete every section
    end try
    repeat with i from 1 to count pages
      if name of applied paragraph style of text 1 of text frame 1 of page i = "Chapter" then
        set chaptertitle to contents of paragraph 1 of text 1 of text frame 1 of page i
       
        set newsec to make new section
        if i = 1 then
          set continue numbering of newsec to false
        else
          set continue numbering of newsec to true
        end if
        set page start of newsec to page i
        set marker of newsec to chaptertitle
      end if
    end repeat
  end tell
end tell
