Don Cragun's little awk script does exactly that - loop through ALL test-?????? files around, where ?????? matches the file names the sample numbers you post: 000000, 000001, 000002, etc.
If - as he explains - the echo command is removed, and the schript's output is piped through sh, all your test files should be renamed according to your spec. That is - if all files contain DIFFERENT strings as $4 in their first line. If not, files with lower numbers might be overwritten by the ones with higher number and identical $4.
EDIT: To avoid that problem, consider this small adaption of Don Cragun's script:
