I don't see an official way to to change the alignment, but looking into the 
source there's

class OptionMenu(Pmw.MegaWidget):

    def __init__(self, parent = None, **kw):

[...]
	self._menubutton = self.createcomponent('menubutton',
		(), None,
		Tkinter.Menubutton, (interior,),
		borderwidth = 2,
		indicatoron = 1,
		relief = 'raised',
		anchor = 'c',
		highlightthickness = 2,
		direction = 'flush',
                takefocus = 1,
	)

so if you don't mind touching _private attributes

          self.vege_menu._menubutton.config(anchor=Tkinter.W)

should work.
