From the man page:
<I>If all the specified keys compare equal, the entire record is used as the final key.</I>
So, we first sort based on field 3, lets say its 1999. To determine the order within the 1999 entries, they are sorted based on the entire record (numerical order). Which would mean (field seperator ignored):
01011999
01021999
01031999
01041999
...
etc

SORT(1) User Commands SORT(1)
NAME
sort - sort lines of text files
SYNOPSIS
sort [OPTION]... [FILE]...
sort [OPTION]... --files0-from=F
DESCRIPTION
Write sorted concatenation of all FILE(s) to standard output.
Mandatory arguments to long options are mandatory for short options too. Ordering options:
-b, --ignore-leading-blanks
ignore leading blanks
-d, --dictionary-order
consider only blanks and alphanumeric characters
-f, --ignore-case
fold lower case to upper case characters
-g, --general-numeric-sort
compare according to general numerical value
-i, --ignore-nonprinting
consider only printable characters
-M, --month-sort
compare (unknown) < `JAN' < ... < `DEC'
-n, --numeric-sort
compare according to string numerical value
-R, --random-sort
sort by random hash of keys
--random-source=FILE
get random bytes from FILE (default /dev/urandom)
-r, --reverse
reverse the result of comparisons
--sort=WORD
sort according to WORD: general-numeric -g, month -M, numeric -n, random -R, version -V
-V, --version-sort
sort by numeric version
Other options:
--batch-size=NMERGE
merge at most NMERGE inputs at once; for more use temp files
-c, --check, --check=diagnose-first
check for sorted input; do not sort
-C, --check=quiet, --check=silent
like -c, but do not report first bad line
--compress-program=PROG
compress temporaries with PROG; decompress them with PROG -d
--files0-from=F
read input from the files specified by NUL-terminated names in file F; If F is - then read names from standard input
-k, --key=POS1[,POS2]
start a key at POS1 (origin 1), end it at POS2 (default end of line)
-m, --merge
merge already sorted files; do not sort
-o, --output=FILE
write result to FILE instead of standard output
-s, --stable
stabilize sort by disabling last-resort comparison
-S, --buffer-size=SIZE
use SIZE for main memory buffer
-t, --field-separator=SEP
use SEP instead of non-blank to blank transition
-T, --temporary-directory=DIR
use DIR for temporaries, not $TMPDIR or /tmp; multiple options specify multiple directories
-u, --unique
with -c, check for strict ordering; without -c, output only the first of an equal run
-z, --zero-terminated
end lines with 0 byte, not newline
--help display this help and exit
--version
output version information and exit
POS is F[.C][OPTS], where F is the field number and C the character position in the field; both are origin 1. If neither -t nor -b is in
effect, characters in a field are counted from the beginning of the preceding whitespace. OPTS is one or more single-letter ordering
options, which override global ordering options for that key. If no key is given, use the entire line as the key.
SIZE may be followed by the following multiplicative suffixes: % 1% of memory, b 1, K 1024 (default), and so on for M, G, T, P, E, Z, Y.
With no FILE, or when FILE is -, read standard input.
*** WARNING *** The locale specified by the environment affects sort order. Set LC_ALL=C to get the traditional sort order that uses
native byte values.
