PyQt QProgressBar vertical text alignment issue

I am trying to change color in vertically aligned QProgressBar

I found example of how to change color by setStyleSheet here: Changing the color of a QProgressbar()

But there is not mentioned vertical alignment. Please check screenshot of my example:

First progress bar is default, second and third is with changed color. but text is not properly aligned (I need it as on first default bar).

I also tried setTextDirection(QtGui.QProgressBar.TopToBottom) but it didn't help.

Please advise

Code to try it out:

import sys
from PyQt4 import QtGui, QtCore

class Window(QtGui.QMainWindow):

    def __init__(self):
        super(Window, self).__init__()
        self.setGeometry(50, 50, 500, 300)

        progress1 = QtGui.QProgressBar(self)
        progress1.setGeometry(50, 50, 25, 150)
        progress1.setOrientation(QtCore.Qt.Vertical)
        progress1.setMaximum(0)
        progress1.setMaximum(10)
        progress1.setValue(4)
        progress1.setFormat("myServer008-Load")

        progress2 = QtGui.QProgressBar(self)
        progress2.setGeometry(100, 50, 25, 150)
        # adding style will stop rotating text 90 degrees clockwise
        progress2.setStyleSheet("QProgressBar::chunk { background-color: red; }")
        progress2.setOrientation(QtCore.Qt.Vertical)
        progress2.setMaximum(0)
        progress2.setMaximum(10)
        progress2.setValue(4)
        progress2.setFormat("myServer008-Load")

        progress3 = QtGui.QProgressBar(self)
        progress3.setGeometry(150, 50, 25, 150)
        # centring text works, but still do no rotate it
        progress3.setStyleSheet("QProgressBar { text-align: center; } QProgressBar::chunk { background-color: red; }")
        progress3.setOrientation(QtCore.Qt.Vertical)
        progress3.setMaximum(0)
        progress3.setMaximum(10)
        progress3.setValue(4)
        progress3.setFormat("myServer008-Load")


app = QtGui.QApplication(sys.argv)
GUI = Window()
GUI.show()
sys.exit(app.exec_())
