okay, for you to know whether the command was successful or not, each of the three scripts have to return come sort of code, like 0 for success and nonzero for failure.

then, you write a wrapper like this

#!/bin/sh

#Try doing "step 1" five times
step1timedout=1
for k in 1 2 3 4 5
do

#STEP 1: CONVERT XML files to PS files
convert_xml_files_to_ps.sh #replace this with your command

#get the return code
retcode=$?

#if success, break from loop
if [ $retcode -eq 0]
then
step1timedout=0
break
fi
done

#Check if step 1 timed out
if [ $step1timedout -eq 1]
then
echo "Step 1 failed to execute after 5 tries, aborting execution..."
exit 255
fi

#STEP 2: CONVERT ALL PS FILES TO PDF FILES
#repeat the code for step 1

#STEP 3: FTPING ALL PDF FILES TO THE SERVER.
#repeat the code for step 1

#end of script
exit 0

Note that this is what the script will do:
1. will try executing step 1. if it is successful, it will proceed for step 2. If step 1 fails after 5 tries, the whole script will exit.
2. Step 2 will execute with the same logic
3. Step 3 will execute with the same logic

Now if you want to repeat the whoel process in a loop, you can put the whole thing in a for loop and so it as many times as you like.

ebook-convert

EBOOK-CONVERT(1)						      calibre							  EBOOK-CONVERT(1)

NAME

       ebook-convert - part of calibre

SYNOPSIS

       ebook-convert  input_file output_file [options]

DESCRIPTION

       Convert an ebook from one format to another.

       input_file is the input and output_file is the output. Both must be specified as the first two arguments to the command.

       The  output ebook format is guessed from the file extension of output_file. output_file can also be of the special format .EXT where EXT is
       the output file extension. In this case, the name of the output file is derived the name of the input file. Note that  the  filenames  must
       not  start  with a hyphen. Finally, if output_file has no extension, then it is treated as a directory and an "open ebook" (OEB) consisting
       of HTML files is written to that directory. These files are the files that would normally have been passed to the output plugin.

       After specifying the input and output file you can customize the conversion by specifying various options. The available options depend	on
       the input and output file types. To get help on them specify the input and output file and then use the -h option.

       For full documentation of the conversion system see http://calibre-ebook.com/user_manual/conversion.html

       Whenever you pass arguments to ebook-convert that have spaces in them, enclose the arguments in quotation marks.

OPTIONS

       --version
	      show program's version number and exit

       -h, --help
	      show this help message and exit
