do you have an object with name "aov" in your directory???
Check with ls()
I recommend to remove it as it is not recommended to give 
objects built in function names.

anova() gives you the result which is maybe more suitable for 
subsetting then summary

try

unlist(anova(anov)[5])[1]
Pr(>F).1 
0.03892554 

it works just with your example, for more dimensions go through 
manual pages and some trial and error.
