The use the paste solution suggested earlier.

file_1 file_2 > file_3
------ ------- ------
111 cat 111 cat
222 dog 222 dog
333 cow 333 cow

paste -d" " file_1 file_2 > file_3
sed -e "s/^/mv /g" ie "s/$/;/g" file_3 > file_4

The chmod 755 for file_4 and run it. You'll have a log of the mappings in file 3 and 4 as well.

mv 111 cat;
mv 222 dog;
mv 333 cow;

But still wont the sort help ... it sorts in the alphabetical order and then we can proceed using the paste command and so on...

what do you want to sort.
when the filenames are random, then you can not generate those filenames using this

secondly, when you are using the paste command, there is no need to sort as the list could be required in any order depending on the the user.
