I haven't followed the whole discussion here, but extracting selected 
problems from the file containing the couple hundred problems may be 
workable -- i.e. separate each problem in the big file with

%SomeSeparator

and copy out only the wanted problems from the big file with a filter --

--- snip ---
#!/usr/bin/perl -w

my @selectedProblems = qw/34 89 27 90/ ; # EDIT list of problems to 
select.
#
use strict ;

my %selectedProblems = () ; # copy list to a hash to use exists() below 
(oh the horror of exposing source!)
foreach (@selectedProblems) {
     $selectedProblems{$_} = "" ;
}

my $counter = 0 ;
my $selectedFlag ;

open(PROBLEMS,"<in.tex") ;	#  EDIT
open(SELECTED,">out.tex") ;  # EDIT
while(<PROBLEMS>) {
     if (/SomeSeparator/) { 	# EDIT to match separator in input file
         $counter++ ;
         $selectedFlag = 0 ;
         $selectedFlag = 1 if exists ($selectedProblems{$counter}) ;
     }
     print  SELECTED $_ if ($selectedFlag == 1) ;
}
exit();
--- snip ---

This, uh, could use a few refinements.

Warm regards,
