You mean figure.  But a source block in not a float.

Consider this minimal example

\documentclass{article}
\usepackage{minted}
\usepackage{capt-of}
\begin{document}
\begin{minted}{lisp}
(+ 1 1 )
\end{minted}
\captionof{listing}{test}
\end{document}

This is the error I get when compiling:

ERROR: Undefined control sequence.

--- TeX said ---
address@hidden ... address@hidden \normalsize address@hidden@capt 
                                                  address@hidden address@hidden
l.8 \captionof{listing}{test}

It works fine when I use another counter than listing.

I guess it doesn't.  In any, minted.sty has

  \RequirePackage{float}

So we can be sure [H] is available.  Thus, we should just rely on float.
