sed using data in two different positions

Shell Programming and Scripting

Hi,
I cannot figure out how to input a greater than command for a item of data that may be in two different positions.

my input file looks like this.

isup,isupmap,2011,05,10
isup,isupmap,2011,05,11
isup,isupmap,2011,05,12
pcap,2011,05,10
pcap,2011,05,11
pcap,2011,05,12

You will see that the first 3 rows are 5 items and the next 3 rows are four items.

What I would like to do is extract the line where the last item greater then 10. Hence the output would be.

isup,isupmap,2011,05,11
isup,isupmap,2011,05,12
pcap,2011,05,11
pcap,2011,05,12

Thanks in advance for any help provided.
