Hi Neerav,
Maybe you can try doing this with an applescript. After you get/select the files somehow in Automator, add the *Run Applescript* action after that. Add this piece of code after the *on run {input, parameters}* line:
repeat with thisFile in input
tell application "Finder"
set fileName to name of (thisFile as alias)
set fileName to (do shell script "echo " & quoted form of fileName & " | sed 's/^[0-9]*//'")
set name of thisFile to fileName
end tell
end repeat
This will delete any numbers that appear in the beginning of the file name. This approach is better than deleting the first three characters in case the numbers aren't padded with leading zeroes.
Anyway, I haven't tested this script myself so back up some files and run it on a such a small sample so that if there are any bugs (I don't expect any) we can remove them.
