Unstable Sort order breaks font-Family

[ChristianLuxem]

Hello,
i want to support also Internet Explorer and therefore i have to do the following things for Fonts:

@font-face {
	font-family: "test";
	src: url("#test.eot");
	src: url("test.eot?#iefix") format("embedded-opentype"),
	url("test.woff") format("woff"),
	url("test.ttf") format("truetype"),
	url("test.otf") format("opentype"),
	url("test.svg") format("svg");
}

What CSSComb does, is the following:
It will do an unstable sort algorithm and therefore the first "src" will sometimes be under the other things. That is bad, because of that the Font will not work properly in Chrome.

How can i fix that?
