I'd consider it neither a bug nor a feature.  Scroll Lock mode is simply
not aware of Isearch mode and it probably doesn't need to be because a
search is not an explicit scrolling command.

For me the current behavior is fine, but if other people think it would
be a good idea for Scroll Lock mode to center search results, I would
not mind adding an option for it.

The only problem is that I could not find an appropriate hook in Isearch
mode which provides a means to recenter the view.  One could perhaps
abuse `isearch-message-function' for that but I don't consider this a
good idea.  Another bad idea would be to advise `isearch-update' like
this:

(defadvice isearch-update (after scroll-lock-isearch-update activate)
  "Recenter view after `isearch-update'."
  (recenter '(4)))
