Well, it might be a poor answer to a poorly formulated question then?
Anyway..

Ah, now I understand your problem. The Trigger event is always thrown, 
even in the DoubleClick case. Hmm, now you found out, why the Trolls 
didn't call the former event just LeftClick ;-), and fixing this would 
shift the issue into DoubleClick handling.

Here's, how I would solve such an issue:

import sys
from PyQt4.QtCore import *
from PyQt4.QtGui import *

class MainWindow(QMainWindow):

    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)
        self.trayIcon = QSystemTrayIcon(QIcon("some.png"), self)
        self.trayIcon.activated.connect(self.onTrayIconActivated)
        self.trayIcon.show()
        self.disambiguateTimer = QTimer(self)
        self.disambiguateTimer.setSingleShot(True)
        self.disambiguateTimer.timeout.connect(
                self.disambiguateTimerTimeout)

    def onTrayIconActivated(self, reason):
        print "onTrayIconActivated:", reason
        if reason == QSystemTrayIcon.Trigger:
            self.disambiguateTimer.start(qApp.doubleClickInterval())
        elif reason == QSystemTrayIcon.DoubleClick:
            self.disambiguateTimer.stop()
            print "Tray icon double clicked"

    def disambiguateTimerTimeout(self):
        print "Tray icon single clicked"


if __name__ == "__main__":
    app = QApplication(sys.argv)
    w = MainWindow()
    w.show()
    sys.exit(app.exec_())
