requireing a script that isn't coded for that situation could override all kinds of data and subroutines in your calling code. also, require will only load a file once. if you are sure that it won't have any strange side-effects, you could probably do 
@ARGV = '-h';
do 'myscript.pl';

However, since that will recompile the code each time, you will not gain optimum performance.

Your best strategy would be to put the shared code in a module and use that in both scripts. See perlmodlib.
