Have they ruled out the possibility that these could be two week old doodles in a 1,300 year old book?

yeah! I don't know how they can date the doodles. Same issue with cave paintings, unless somehow they can date the paintings

  Cave paintings they date by the layering above and below the applied material. Newly applied pigment doesnt have a deposit on top and is distinct from the age and structure of the substrate. Contemporary information comes from things like the age of the smoke marks maybe: burnt things fix their C14? I imagine in this case there's a bunch of supporting forensics about these marks.

  Cave paintings have been dated via radio carbon of organic structures built over the paintings .. eg: Gwion paintings in the Kimberley were created around 12,000 years ago, wasp nests suggest Enigmatic human figures with elaborate headdresses, arm and waist decorations adorn rock shelters in the Kimberley region of Western Australia. This style of art, known as Gwion, Kiro Kiro or Kujon, was painted by the ancestors of today's traditional owners around 12,000 years ago, a new study suggests. The date of the art work, published today in the journal Science Advances, is based on radiocarbon dating of mud wasp nests. https://www.abc.net.au/news/science/2020-02-06/gwion-rock-art-in-kimberley-dated-using-wasp-nests/11924584 https://www.abc.net.au/news/science/2020-02-06/gwion-rock-ar... Other methods exist, eg: Calcite deposits covering ancient artworks deep within limestone caves in other parts of the world such as Borneo have been reliably dated using a technique that measures how fast uranium decays into thorium. But Australian rock art is painted on sandstone — which contains no calcite — and they are in overhangs exposed to the elements.

  Measurement of radioactive decay leads to abilities some may consider to be... unnatural.

I would have said it doesn't seem very likely that someone would have gone into a library and doodled on a book in Old English, but this is in Oxford.
