 find stampfile -newer $file

indeed, according to the documentation, the predicate is true if
stampfile is strictly newer than $file.  So the implementation would
have to be something like:

# is_younger FILE FILES
# ---------------------
# Check that FILE is younger than all the FILES.
#
is_younger ()
{
  a_status=0
  a_file=$1
  shift
  for a_f in "$@"
  do
    a_list=`find "$a_file" -newer "$a_f"`
    if test x"$a_list" != x"$a_file"; then
      a_status=1; break
    else :
    fi
  done
  return $a_status
}

Was something wrong with my proposal?

# is_younger FILE FILES
# ---------------------
# Check that FILE is younger than all the FILES.
is_younger ()
{
  test x`find "$@" -newer "$1"` = x
  return $?
}
