Why do you want to use diff ?
You can simply use if :
Code:
#!/bin/sh
a=`wc -l <asdf.x` 
b=`cut -d',' -f5 <asdf.y | grep -v '^$' | wc -l`
if [ $a -ne $b ]
then
   echo "Difference found : $a / $b"
fi

The code in one line :
Code:
[ `wc -l <asdf.x` -ne `cut -d',' -f5 <asdf.y|grep -v '^$'|wc -l`] && echo "Difference found"

Another solution using awk :
Code:
awk -F, '
   NR==FNR { ++count_1 ; next}
   NF>0 { ++count_2;}
   END { if (count_1 != count_2) printf("Difference found : %d / %d", count_1, count_2) }
   ' asdf.x asdf.y
