In my experience, after ORD custom, the recheck area just "flip" your bags over the belt either 1 or 2 (depends on your final designation), so no new tags.
Note: other airport handled differently, like NRT, always have new tag.
And now CX has "Orange Transit Arrow" oneworld priority tag, now CX will put the CX tag along with oneworld tag, so you will be fine.
