Wrong MW3 did not search on ping/latency alone it part of the reason why the game plays bad.
It used a geolocation tool to search for games on top of ping also did some funny stuff when playing in a party (which was patched out). Which the devs did not come out and say was true until they was forced. They changed some of the matchmaking but it still in a poor state.
Fun fact BO1 started goelocation matchmaking.
COD4/WAW/MW2 and BO2 all use the same ish matchmaking system with some small changes which is ping based.
COD4 matchmaking problems was due to the QoS rating US players higher compared to EU players. (IW never patched that out)
All COD games when searching say looking for game within < 50ms
