I've run into this problem before myself, and I'd like to know why it
doesn't work too...

IIRC, "Query replace:" is the prompt for emacs's query-replace
function, NOT query-replace-regexp, which is NOT the same.  The former
will query/replace an exact string, while the latter will
query/replace a regular expression.  I also disagree that C-M means
meta, as only M (as in M-x) should refer to meta.  I suspect that the
C-M key binding is one that just doesn't make sense on PC keyboards,
but I don't know that for a fact.  

If you don't have query-replace-regex mapped to another key sequence
that will work for you, you can execute it with emacs's
"execute-extened-command" function, usually bound to M-x by default:

  M-x query-replace-regexp
 
This will indeed respond with the prompt "Query replace regexp:"

HTH.
