I cannot reproduce your results. I get the same plot in both:

In[3]:= $Version

Out[3]= 8.0 for Mac OS X x86 (64-bit) (October 5, 2011)

and

In[3]:= $Version

Out[3]= 9.0 for Mac OS X x86 (64-bit) (November 20, 2012)

I notice with the default coloring and default PointSize it
might be easy to miss the point being plotted since the
GridLines specification has the grid lines crossing where the
point is plotted.

Try

opts = {Frame -> True, PlotStyle -> {Red, PointSize[.02]},
    GridLines -> {{1}, {1}}};
ListPlot[{{1, 1}}, opts]

just to make it more apparent the point is actually being plotted.
