You could use back tics instead.

$results = `osascript -e 'tell app \"System Events\" to count processes 
whose name is \"firefox-bin\"'`

Otherwise, pipe it to a temp file.  The exec instead of system
should be looked to know all three ways of invoking commands
outside of perl.  I prefer backtics, and the return value can
be an array of records.

system("osascript -e 'tell app \"System Events\" to count processes whose name is \"firefox-bin\"' > /tmp/myscript_datetimestamphere"

open (IN, "</tmp/myscript_myscript_datetimestamphere" )
my @standardout = <IN>;
close IN;

Must do:
Also, check $! to check that system returns no error.
