Sort a las file keep the header as it is

I have several las files with a header and each file start Version and text and before the data starts end up with ~Ascii, then the numbers starts:
-------------------------------------------------------------------------

Code:
~Version
.....text....
~Ascii
2 abc 230 1 name
1 abc 400 1 name2
3 abb 350 2 name

----------------------------------------------------------------------------
What I want to do is to keep the header as it is and sort with the first column
the result to look something as following :
Code:
~Version
.....text....
~Ascii
1 abc 400 1 name2
2 abc 230 1 name
3 abb 350 2 name

and if it is possible to run for all files in one go, since all the files are *.las file?

thank
T

ASCII-XFR(1)							Linux Users Manual						      ASCII-XFR(1)

NAME
ascii-xfr - upload/download files using the ASCII protocol SYNOPSIS
ascii-xfr -s|-r [-ednv] [-l linedelay] [-c characterdelay] filename DESCRIPTION
Ascii-xfr Transfers files in ASCII mode. This means no flow control, no checksumming and no file-name negotiation. It should only be used if the remote system doesn't understand anything else. The ASCII protocol transfers files line-by-line. The EOL (End-Of-Line) character is transmitted as CRLF. When receiving, the CR character is stripped from the incoming file. The Control-Z (ASCII 26) character signals End-Of-File, if option -e is specified (unless you change it to Cotrol-D (ASCII 4) with -d). Ascii-xfr reads from stdin when receiving, and sends data on stdout when sending. Some form of input or output redirection to the the modem device is thus needed when downloading or uploading, respectively. OPTIONS
-s Send a file. -r Receive a file. One of -s or -r must be present. -e Send the End-Of-File character (Control-Z, ASCII 26 by default) when uploading has finished. -d Use the Control-D (ASCII 4) as End-Of-File character. -n Do not translate CR to CRLF and vice versa. -v Verbose: show tranfer statistics on the stderr output. -l milliseconds When transmitting, pause for this delay after each line. -c milliseconds When transmitting, pause for this delay after each character. file Name of the file to send or receive. When receiving, any existing file by this name will be truncated. USAGE WITH MINICOM
If you want to call this program from minicom(1), start minicom and go to the Options menu. Select File transfer protocols. Add the fol- lowing lines, for example as protocols I and J. I Ascii /usr/bin/ascii-xfr -sv Y U N Y J Ascii /usr/bin/ascii-xfr -rv Y D N Y AUTHOR
