GPG will use the most recent valid subkey for a given purpose (i.e.  
the most recent valid signing key, the most recent valid encryption  
key).  If you want to force the use of a particular key, instead of  
specifying your key as XXXXXXX (the key id), specify the exact key or  
subkey you want as XXXXXXXX! (the key id plus an exclamation mark).
