Use this definition

\define[2]\ChapterCommand
  {\framed
     [frame=off,bottomframe=on,framecolor=orange,width=fit]
     {#1\hspace[medium]#2}}


In newer versions (the environment form was added a few months ago) you can use

  \startframed … \stopframed

instead of

  \framed{…}

which makes it easier to format code when \framed has more content.
