The problem lies with mathdesign::
%% ----------------------------------------------------------------
%% Encoding is automatically set to T1
%% ----------------------------------------------------------------
\RequirePackage[T1]{fontenc}
The workaround is to re-set the TeX font encoding to EU1 (or U, if you use
LuaTeX). The following example:
\documentclass[english]{article}
\usepackage{fontspec}
\usepackage{xunicode}
\usepackage{polyglossia}
\setdefaultlanguage{english}
\usepackage[mdugm]{mathdesign}
%% Mathdesign sets font encoding to T1, reset with one of:
% \RequirePackage[EU1]{fontenc}
\renewcommand{\encodingdefault}{EU1}
\setmainfont[Mapping=tex-text]{Comic Sans MS}
\begin{document}
Was ist das?
\[
2^{2}=4
\]
\end{document}
results in mathdesign math and comic text fonts.
