This is because ps-mode.el binds [return] in addition to "\r":

  (define-key ps-mode-map "\r" 'ps-mode-newline)
  (define-key ps-mode-map [return] 'ps-mode-newline)

whereas isearch.el binds only "\r":

  (define-key isearch-mode-map "\r" 'isearch-exit)

We could remove the [return] keybinding from ps-mode.el,
but there are many other places that bind [return] and [backspace]
in the Emacs source tree, external packages as well as in
countless user init files, so maybe better would be to add [return]
and [backspace] keybindings to isearch-mode-map in isearch.el.
