IE overrides MIME types for more then just ambiguous types, to quote one test mentioned in the appendix
"If the server-provided MIME type is either known or ambiguous, the buffer is scanned in an attempt to verify or obtain a MIME type from the actual content. If a positive match is found (one of the hard-coded tests succeeded), this MIME type is immediately returned as the final determination, overriding the server-provided MIME type (this type of behavior is necessary to identify a .gif file being sent as text/html)."
