matplotlib creates a prototypical tick (the prototick) and then
creates new ones on as as needed basis, copying properties from the
prototick.  Of course, position is one of the properties that cannot
be copied, which is why you are having trouble in your example.
Fortunately, there is an easy solution.

Call ax.xaxis.get_major_ticks() and access the label attribute:

for tick in ax.xaxis.get_major_ticks():
   label = tick.label1

Axis.get_major_ticks  will force a call to the locator and update the
tick list.  The Axes methods like get_xticklabels are just working on
the existing tick list rather than calling the get_major_ticks method
which is why you are not getting the full list.  This is a bug.  I
just made changes in svn so that all the accessor methods
(ax.get_xticklines, ax.get_yticklabels, and friends) all trigger a
call to axis.get_major_ticks rather so they should give the same
results going forward.

FYI, the Tick attributes are:

      tick1line  : a Line2D instance
      tick2line  : a Line2D instance
      gridline   : a Line2D instance
      label1     : a Text instance
      label2     : a Text instance
      gridOn     : a boolean which determines whether to draw the tickline
      tick1On    : a boolean which determines whether to draw the 1st tickline
      tick2On    : a boolean which determines whether to draw the 2nd tickline
      label1On   : a boolean which determines whether to draw tick label
      label2On   : a boolean which determines whether to draw tick label
