The position of the legend is determined at drawing time, so it is a
bit tricky to get it right.
I recommend you to use "annotate" instead.
ax = subplot(111)
ax.plot([1,2,3], label="u=2,p=3")
leg = ax.legend()
ann = ax.annotate("Test 2", xy=(0.5, 1.), xycoords=leg.get_frame(),
xytext=(0,10), textcoords="offset points",
va="center", ha="left",
)
ann.set_zorder(leg.get_zorder()+0.1)
# the zorder of ann must be higher than leg so that the position of
leg is known when ann gets drawn
See here for some more details.
