Are event subscribers called in order of subscription?

Is it safe to assume that event subscribers are called in order of subscription?
Example:

void One(object sender, EventArgs e) {}
void Two(object sender, EventArgs e) {}

event EventHandler foo;

foo += One;
foo += Two;

Is One() always called before Two() when the event is fired?

Edit:
You should ofcourse not rely on it, I was just thinking. The idea was, that multicast delegates are similary to the COMMAND pattern. So I was just wondering. Ususally you would use a collection that keeps the order for COMMANDs so you can do undo/redo/whatever.
