Fx.CSS search fails in Internet Explorer

[rloaderro]

Internet Explorer (7) switches the order of multiple classes, so if my stylesheet has:

.apple.orange { ... }

Internet Explorer manages it as:

.orange.apple { ... }

Therefore FX.CSS search, which compares selectors with...

selectorText.test('^' + selector + '$')

...fails for IE. ATM I am writing my styles as:

.apple.orange,
.orange.apple { ... }

But it would be great if Mootools could test independent of class order, or detect and switch for IE.
