a 'show label' will tell you that you have defined a whole bunch of labels,
because each 'set label' creates a new label.
but - each label has also a tag (see 'help label')!

so, modifying your script so that your labels have defined tags
will result in modified labels:

set label 1 'Packet Count: $total_packets' at 1,1;
set label 2 'Total Retransmits: $total_retrans' at 1,1.5;

'help set label' gives an answer:

and 'help coordinates' tells you:

set label 1 "abc" at graph 0.5,0.95 center

will place your label centered in the middle of the x axis just below the
upper y axis.
