If you refer to the end of TUS 9.0 Section 16.1 you will find mention of U+0331 COMBINING MACRON BELOW and U+0303 COMBINING TILDE, which are thus candidates for scx ∍ Latn. One might also consider U+0359 COMBINING ASTERISK BELOW; I have seen the combination ช͙ <U+0E0A THAI CHARACTER CHO CHANG, U+0359> used in a phonetic symbol for English, representing [ʒ]. As their scx values are 'Inherited', should their values not be treated as though they already included Thai? I suppose, though, that they do not in fact match "p(scx=Thai)". There does seem to be a view that scx=inherited is shorthand for some list of European scripts. Richard.
