You could try the following:

--8<---------------cut here---------------start------------->8---
(services
 (append
  (list
   (modify-services %desktop-services
     (log-rotation-service-type
      config =>
      (log-rotation-configuration
       (inherit config)
       (external-log-files '("/var/log/cups/access_log"
                             "/var/log/cups/error_log"
                             "/var/log/cups/page_log"))))))))
--8<---------------cut here---------------end--------------->8---

With modify-services the contents of %base-services or %desktop-services
are modified.
