I think you want ownnumber (in addition to the previously mentioned 
\section).

    \setupcolors[state=start]
    \define[2]\MySectionCommand
       {\framed
          [frame=off,
           width=\textwidth,
           align={right},
           background=color,
           backgroundcolor=lightgray]
          {#1.\quad#2}}

    \setuphead[section][command=\MySectionCommand,ownnumber=yes,numbercolor=red]

    \setupbodyfont[palatino,12pt]

    \starttext

    \placecontent

    \section{A}{Définitions}
    \input knuth

    \section{1}{Propriétés}
    \input knuth

    \section{2}{Propriétés}
    \input knuth

    \section{3}{Propriétés}
    \input knuth

    \section{B}{Définitions}
    \input knuth

    \section{1}{Propriétés}
    \input knuth

    \section{2}{Propriétés}
    \input knuth

    \stoptext
