Thank you to Vinod Kumar for taking the trouble to reply to me
(off-list). On re-reading, I see that 'logical order' is defined in TUS
6.2 Section 2.2 and is none other than the order to be used for Unicode
text. I apologise for wasting people's time.

For me, the relevant consequence of this is that every script whose
Unicode usage is conformant, *including Thai*, is stored in logical
order. I qualify my statement because I will be totally unsurprised to
find scripts for which most allegedly Unicode-encoded text is stored in
visual order simply because renderers are unavailable.
