Check if this works: 
my $line = '%TMP%\$$(DATE)_RE_IRD_Soc';
my $line2 = '%RESULTS%\$$(DATE_USA)' ;
my $line3 = '%RESULTS%\$$(1110_DATE_USA)';
@lines=($line,$line2,$line3);
foreach $elem (@lines)
{
        if($elem=~m/.*\$\$(\(.*\))(.*)?/)
    {
            print "\nFirst: $1, Second: $2";
    }
}
