[Tagging] Extremely complicated conditional values

I'd try something similar to this example:

access:conditional=destination @ (weight>5.5)

So in your case you would have

maxspeed:advisory:conditional=18 @ (weight>=37.5)
maxspeed:advisory:conditional=22 @ (weight>=35 AND weight<37.5)
maxspeed:advisory:conditional=26 @ (weight>=32.5 AND weight<35)
maxspeed:advisory:conditional=37 @ (weight>=30 AND weight<32.5)

(... the standard for weight being short tons in the USA...)
