:) -- BIG BROTHER IS WATCHING YOU!
Below I place a legal way to do it -- with examples.
I hope you understand how to customize it.
It may be more close to what was asked for than Tom's

My code furthermore assumes that no nesting of such
environments is required. Note the similarity to the
{thebibliography} environment. Indeed,

\newenvironment*{enumileftaligned}[1][0]
{\renewcommand{\section}[5]{}\thebibliography{#1}}
{\endthebibliography}

is another hack working as well on my installation.
If you use \bibitem then in place of \item,
you can refer to items by \cite. [:)]
(Well, I haven't thought much about several such lists
in one document, and I won't any more. That package
managing several bibliographies in one document
may help.)

\noindent
Usually:
\begin{enumerate}
\item One item.
\setcounter{enumi}{9}
\item Skipped a few items.
\end{enumerate}
Left-aligned (cf. \verb|\thebibliography|):
\begin{enumileftaligned}
\item One item.
\item Another item.
\item Once again.
\end{enumileftaligned}
More than 9:
\begin{enumileftaligned}[00]
\item One item.
\item Another item.
\setcounter{enumi}{9}
\item Skipped a few items.
\end{enumileftaligned}
Or do you prefer:
\renewcommand{\leftaligninglabel}{\hspace{\fill}}
\begin{enumileftaligned}[00]
\item One item.
\item Another item.
\setcounter{enumi}{9}
\item Skipped a few items.
\end{enumileftaligned}

\end{document}
