The following example fails.

Thanks for the quick fix.

Why do orientation and rotate produce different results? Example:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\startbuffer [te]
	\starttext
		\framed[width=5cm,height=2cm,rulethickness=3pt,align=right]{\tfd Foo}
	\stoptext
\stopbuffer

\starttext
	\startplacefigure [title=Orientation]
		\externalfigure [te] [orientation=90, frame=on]
	\stopplacefigure

	\startplacefigure [title=Rotation]
		\rotate[rotation=90]{\externalfigure [te]}
	\stopplacefigure
\stoptext
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

I guess it comes from this part in pack-rul.mkiv, when you rotate the box by 90 or 270 degrees
context switches the width and height of the framed box (which is also used by \externalfigure)
but as you can see he does this first in \pack_framed_start_orientation and a second time in
\pack_framed_stop_orientation_odd.

\def\pack_framed_start_orientation
  {\ifcase\p_framed_orientation
     \let\pack_framed_stop_orientation\relax
   \else
     \scratchcounter\p_framed_orientation % weird .. why
     \divide\scratchcounter\plustwo
     \ifodd\scratchcounter
       \swapmacros\framedwidth\framedheight
       \swapmacros\localwidth\localheight
       \swapdimens\d_framed_height\d_framed_width
       \let\pack_framed_stop_orientation\pack_framed_stop_orientation_odd
     \else
       \let\pack_framed_stop_orientation\pack_framed_stop_orientation_even
     \fi
   \fi}

% why are the dimensions swapped again, this was already done above

\def\pack_framed_stop_orientation_odd
  {\swapmacros\framedwidth\framedheight
   \swapmacros\localwidth\localheight
   \swapdimens\d_framed_height\d_framed_width
   \pack_framed_stop_orientation_even}

these three can go (forgotten to delete them when splitting)

Brilliant, that did the trick. One  thing more: Is is by design that
only  multiples of  90° work?  89 degrees  results in  totally wrong
spacing. Example (your fix is already applied):

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\startbuffer [te]
	\starttext
		\framed[width=5cm,height=2cm,rulethickness=3pt,align=right]{\tfd Foo}
	\stoptext
\stopbuffer

\starttext
	\startplacefigure [title=90°]
		\externalfigure [te] [orientation=90, frame=on]
	\stopplacefigure

	\startplacefigure [title=89°]
		\externalfigure [te] [orientation=89, frame=on]
	\stopplacefigure
\stoptext
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Can be related to the buffer because the direct way looks good.

\starttext
	\startplacefigure [title=90°]
		\framed[orientation=90]{\framed[width=5cm,height=2cm,rulethickness=3pt,align=right]{\tfd Foo}}
	\stopplacefigure

	\startplacefigure [title=89°]
		\framed[orientation=89]{\framed[width=5cm,height=2cm,rulethickness=3pt,align=right]{\tfd Foo}}
	\stopplacefigure
\stoptext

With \framed it works, but with \externalfigure it's messed up:

\starttext
	\startplacefigure [title=90°]
		\externalfigure [cow] [orientation=90, frame=on]
	\stopplacefigure

	\startplacefigure [title=89°]
		\externalfigure [cow] [orientation=89, frame=on]
	\stopplacefigure
\stoptext
