A low sunshine total at Lerwick and a very high percentage at Kirkwall
seems like an unlikely combination. Could one figure or the other be in
error?

No, John ... the Lerwick figure, although the smallest in the country, was
still 175% of the local average! They don't get much sunshine that far
north in December ...

Plugging their latitude into my sunrise/sunset calculator, they only get
5h45m of daylight in midwinter!
