Here's a bash snippet to list the text files (only text files, no binaries) in the current directory sorted by line count:
find . -depth 1 -type f -exec grep -Il "" {} \; | xargs wc -l | sort
This outputs something like:
6 ./alexa.h
35 ./Astrid.h
70 ./Henrick.sh
74 ./dagmar.h
133 ./Adrea.cpp
168 ./max.cxx
216 ./Sabina.cpp
2339 ./Thorsten.cpp
39991 ./albrecht.off
Update: For the particular case of wc
(and maybe) others its faster to do this:
wc -l `grep -Il "" *` | sort
