He probably uses the ugly pgf bullets that come with beamer. This is tricky to 
achieve. For the round bullets:

In preamble:

\newcommand\myenum[1]{%
  \begin{pgfpicture}{-1ex}{-0.65ex}{1ex}{1ex}
    \usebeamercolor[fg]{item projected}
    {\pgftransformscale{1.75}\pgftext{\normalsize\pgfuseshading{bigsphere}}}
    {\pgftransformshift{\pgfpoint{0pt}{0.5pt}}
      \pgftext{\usebeamerfont*{item projected}#1}}
  \end{pgfpicture}%
}

and then

[\myenum{3}]
instead of
[3]
