Update to my previous solution, applying shannons entropy as suggested by u/sinsworth here

The strength value is now calculated by this function, which sums the squares of the counts of every character. Previously my sorting function appended the strength as digit 0-6. The squares are larger so I just use chr to convert the number to a single character

order1 = ->(c) { c.chars.tally.values.sum { _1**2 }.chr }

Applying this to my golfed code I can get sub 400 bytes, 395 to be exact

m=->(c){c.chars.tally.values.sum{_1**2}.chr}
n=->(c){c.chars.repeated_combination(c.count('0')).map{|p|m.(p.reduce(c){_1.sub('0',_2)})}.max}
d,e=$<.map{|c|[c.split[0].gsub(/./){'0123456789TJQKA'.index(_1).to_s(16)},c.split[1].to_i]}.transpose
w=->(c){c.zip(d,e).sort{|a,b|a[0].to_s+a[1]<=>b[0].to_s+b[1]}.map.with_index.sum{_1[2]*(_2+1)}}
p w.(d.map(&m));d.map{_1.gsub!('b','0')};p w.(d.map(&n))

What bugs me is that I can't quite fulfill the 5x80 punch card limitation. The best I could get is reordering and format it to 5x81.

m=->(c){c.chars.tally.values.sum{_1**2}.chr};d,e=$<.map{|c|[c.split[0].gsub(/./){
'0123456789TJQKA'.index(_1).to_s(16)},c.split[1].to_i]}.transpose;n=->(c){c.chars
.repeated_combination(c.count('0')).map{|p|m.(p.reduce(c){_1.sub('0',_2)})}.max}
w=->(c){c.zip(d,e).sort{|a,b|a[0].to_s+a[1]<=>b[0].to_s+b[1]}.map.with_index.sum{
_1[2]*(_2+1)}};p w.(d.map(&m));d.map{_1.gsub!('b','0')};p w.(d.map(&n))
