Using quotes inside sageplot environment in SageTeX

Question

Here's the question: how do I get the following to work in SageTeX? The quotes always lead to an error.

\sageplot{plot(cos(x),(x,0,pi),label='$\cos(x)$')}

Double quotes, escaping them, ... nothing seems to work.

I don't know enough to tell you what's going on, but this works:

\documentclass{article}
\usepackage{sagetex}
\begin{document}
\pagestyle{empty}
\begin{sagesilent}
G=Graphics()
var('x')
G+=plot(cos(x),(x,0,pi),label='$\cos(x)$')
\end{sagesilent}
\[ \sageplot{G}\] 
\end{document}

Note, to get even more control over the placement of your text label try this:

\documentclass{article}
\usepackage{sagetex}
\begin{document}
\pagestyle{empty}
\begin{sagesilent}
G=Graphics()
H=Graphics()
var('x')
G+=plot(cos(x),(x,0,pi))
H+= text("$\cos(x)$", (3, 1), fontsize=16, color='black')
\end{sagesilent}
\[ \sageplot{G+H}\] 
\end{document}

The people at AskSage will know what's best. Here's output from the first set of code:
