It works out of the box but you have to enable enumeration titles using 
`title=yes` key while defining the enumeration...

\startuseMPgraphic{FunnyFrame}
     picture p ; numeric w, h, o ;
     p := textext.rt("\wrappedcurrentconstruction");

     w := OverlayWidth ; h := OverlayHeight ; o := BodyFontSize ;
     p := p shifted (2o,h-ypart center p);
     draw p ;

     path b;
     b := boundingbox p enlarged (o/10);

     drawoptions (withpen pencircle scaled 1pt withcolor .625red) ;
     draw (2o,h)--(0,h)--(0,0)--(w,0)--(w,h)--(xpart urcorner b,h) ;
     draw b;

     setbounds currentpicture to OverlayBox ;
\stopuseMPgraphic

\defineoverlay[FunnyFrame][\useMPgraphic{FunnyFrame}]

\defineframedtext
   [FunnyFramedText]
   [
     frame=off,
     background=FunnyFrame,
     offset=\bodyfontsize,
     width=\textwidth,
   ]

\defineenumeration[Counter]
   [
     title=yes,
     alternative=empty,
     before=\startFunnyFramedText,
     after=\stopFunnyFramedText,
   ]

\starttext
\startCounter[title={Residue Theorem}]
   Coming back to the use of typefaces in electronic
   publishing: many of the new typographers receive their
   knowledge and information about the rules of typography from
   books, from computer magazines or the instruction manuals
   which they get with the purchase of a PC or software.
