Does XeTeX not consistently support the use of the decimal comma ?

No. Within the extended \font microsyntax, comma separates multiple settings for a feature (something that's only applicable to AAT features, IIRC). It will not be interpreted as a decimal separator.

(Actually, when parsing non-AAT features, it may be treated the same as semicolon - I don't recall for sure.)

Empirically I have found that :

\font \currentfont = "Old English Text
MT/I:color=cf0000;embolden=1,5;slant=0,2"
\currentfont Text

does not give the same results as

\font \currentfont = "Old English Text
MT/I:color=cf0000;embolden=1.5;slant=0.2"
\currentfont Text
