Probably the most efficient way:

my $rev = reverse $_;
if ( $rev =~ /(\d+)=EULAV/ ) {

Firstly you don't need the {1} in there. All it's
doing is insisting that there is only one equals
character, which an unquantified /=/ will do anyway.

To find the last occurrence, just chew up as many
characters as possible from the object string first:

  /.*VALUE=(\d+)/

HTH,
