How to sort key,value pair by value(In ascending)

[ksgupta misc]

Hi,

I have the content like
*10103*,1042279,*4*
*10070*,1001089,*5*
*10102*,1015504,*7*
*10080*,1024369,*7*
*10050*,1025671,*1*
...
from which i separated the key,value pairs and got the output after a single
map and reduce as follows:

10050  1
10070  5
10080  7
10102  7
10103  4
...

I require to sort the output<key,value> pair by value (In ascending order).
Please let me know how can i go ahead.

Required output:
10050  1
10103  4
10070  5
10080  7
10102  7

Thanks in advance,
