Thanks a lot Willi,

Sorry for the late reply. Actually, for a while I couldn't make it work.
But It seems it was just my \dosetuparrangement that was wrong.

Now it works. Here it is, cleaned-up:

\installpagearrangement 2*5*double*2*5
{\dosetuparrangement{2}{5}{10}{3}{6}
 % number of pages on the x axis,
 % number of pages on the y axis,
 % total (?),
 % number of cutmarks on the x axis,
 % number of cutmarks on the y axis,
 \pusharrangedpageTWOFIVEDOUBLESIDED\poparrangedpagesAB\relax}
\def\pusharrangedpageTWOFIVEDOUBLESIDED#1%
{\advancearrangedpageN
\reportarrangedpage\arrangedpageN
\ifcase\arrangedpageN
\or \handlearrangedpageXandY{#1}000\arrangedpageA % 1
 % Numbers starting from 0:
 % rotation state,
 % horizontal placement,
 % vertical placement.

\definepapersize[Vignette][width=80.0mm,height=50.0mm]

\setuplayout

My aim is to have something as plain as possible
so I can modify it quickly to print double-sided cards, more likely from an image,
instead of using some clumsy wysiwyg editor.
Next thing is to find a sensible name for the layout. I'm not sure about the 2*5*double*2*5 name.
Thanks again.
