CompositePresentationEvent order of execution

If i publish multiple events in a single threaded environment, in what order will the subscribers be invoked?

for intance,

Event 1

UpdateCartEventArgs args = new UpdateCartEventArgs (param);
eventAggregator.GetEvent<UpdateCartEventArgs >().Publish(args);

Event 2

eventAggregator.GetEvent<RunTotalEvent>().Publish(
                     new RunTotalEventEventArgs(param));

In which order will the subscribers be called? Is it guarenteed (in a single threaded environment) that Event 1's subscriber will be invoked before event 2?
