It seems that I just hit a very hard to solve issue which needs
not yet available support from the luatex side.
Patricks solution seems not very practical and error prone, so I
settled with this ugly but still readable workaround:
\def\cmd
  {\newdimen\mydimen
   \mydimen=50pt}
\starttexdefinition action
  \cmd
  \startluacode
      if tex.dimen.mydimen < tex.dimen.textwidth then %
      	context("is smaller")
      else %
      	context("is not smaller")
      end %
  \stopluacode
\stoptexdefinition
\action
Is there a good reason why you put \newdimen because dimen/count etc. registers should always be defined once.
