下面是我做的， 分类 + 排序，

@echo off
setlocal EnableDelayedExpansion
 
del b.txt&del 1.txt&del 2.txt
for /f "usebackq delims=" %%i in (`more a.txt`) do (
  for %%j in (%%i)do (
    set "number=   %%j"
    echo !number:~-4!>>1.txt
  )
)
for /f "usebackq" %%i in (`sort 1.txt`) do (
  echo %%i>>2.txt
)
del 1.txt
for /l %%i in (0,1,9) do (
	set /a input=0
	for /f "delims=" %%j in (2.txt) do (		
		set /a num=%%j
		set /a flag=!num:~-1,1!
		if !flag! equ %%i (
			if !input! equ 0 (
				set /p=!flag! <nul>>b.txt	
			)
			set /a input=1
			set /p=!num! <nul >>b.txt
		)
	)
	if !input! equ 1 (
		echo. >>b.txt	
	)
)
start b.txt
del 1.txt&del 2.txt
exitCOPY

   for %%j in (%%i) do (
       set str=%%j
       for /l %%a in (0,1,9) do (
       if "!str: ...

set真是用的经典，学习了。
