Screen readers work with MathPlayer, the IE plugin that my company gives away for free. (I could not tell you which ones and which versions work.) If MathPlayer is installed, IE uses it to display MathML and screen readers use it to turn math into text to be spoken. If the page uses MathJax, and MathJax detects IE+MathPlayer, it defers to MathPlayer to display the math and screen readers will work fine on the math.
