This would be my solution. 
use constant LONG_COUNT => 14;
use constant SHORT_COUNT => 9;

my $some_variable;

# ...

my $loop_count = $some_variable eq 'x' ? LONG_COUNT : SHORT_COUNT;

for $i (0 .. $loop_count) {
   # do some stuff
   print $i;
}

You might even get rid of loop_count and use (0 .. $some_variable eq 'x' ? LONG_COUNT : SHORT_COUNT) directly.

Now LONG_COUNT and SHORT_COUNT will be easy to find and you can document them at the use constant.
