This is surprisingly difficult. In the following code, I've defined a custom node shape square that inherits from the rectangle shape, but forces its size to be square. Unfortunately, the inheritance mechanism doesn't allow redefinition of inherited saved anchors, so I had to copy some code from the TikZ rectangle definition.
On the plus side, it should be correct in all cases (defining different values for inner [xy]sep, minimum {width,height} and outer [xy]sep) and has all the anchors of the rectangle shape.

What about:
\documentclass[tikz]{standalone}
\usetikzlibrary{graphs, graphs.standard}
\begin{document}
\begin{tikzpicture}
\graph [nodes={draw, circle}, clockwise, radius=3in, nodes, n=12, edge={bend left=12}] {
subgraph C_n [name=outer]
};
\end{tikzpicture}
\end{document}
Edit: after again reading your question, I found that you want to start with 0. So, possibly this is an acceptable solution:
\documentclass[tikz]{standalone}
\usetikzlibrary{graphs, graphs.standard}
\begin{document}
\begin{tikzpicture}
\graph [nodes={draw, circle, minimum width=.25in, inner sep=0pt}, clockwise, radius=1in, nodes, n=12, V={0,...,11}, ->, edge={bend left=10,>=stealth}] {
subgraph C_n [name=outer]
};
\end{tikzpicture}
\end{document}

I changed it little bit, like the background with color instead of dotted, but the exact same illustration can be done in Tikz. My illustration is below.
