No, this does not work, doing so I have just plain A, U etc. instead of
umlauted and accented ones.

This works! I did not use texfont (will try it soon, now we celebrate 10 years
of
Ukraine "independence" so I'm mostly hanging around looking at fireworks and
such).
I manually copied utmr8t.tfm to ec-utmr8a.tfm, 
created file foo.map (just to try) with lines like
  ec-utmr8a <ec.enc <utmr8a.pfb
and loaded it with loadmap[foo], and here I have all accents in proper places.

However, I still wonder why the old method did not work.
After 
  \definetypeface[tms][rm][serif][times][default][encoding=ec]
  \usetypescript[berry][ec]
  \setupbodyfont[serif,tms]
I got that \characterencoding is @default@, not @ec@, while
\usetypescript[berry][ec] implies that \Adiaeresis is \@ec@Adiaeresis, not
\@default@Adiaeresis.
I guess this is because some @@fontencoding becomes @default@ while defining
typeface in such a way, despite [encoding=ec].
I see inconsistency here. Or there isn't?

I want to learn a way to use some cyrillic fonts, maybe in different encodings,
and make it as seamless as possible, that's why I'd wish to do it the *right*
way, not just working somehow.
