you need to tell matplotlib to use another font. E.g.

sage: import matplotlib
sage: matplotlib.rc('font', **{'sans-serif' : 'Arial','family' : 'sans-serif'})
sage: list_plot(zip([1..5],[1..5])), True, color='blue', axes_labels=[u'$H,$ км',u'$\mu, c$'])

shows axis labels in cyrillic.
This works on OSX 10.6.8 -- you might need to use a different font on
your system.

To combine this with sagetex, you'd need to put
import matplotlib
matplotlib.rc('font', **{'sans-serif' : 'Arial','family' : 'sans-serif'})
right after
\begin{sagesilent}
