Same historical issue with decimal-fraction SA scores is solved by:

     condition   = ${if >{$spam_score_int}{30}{1}{0}}


Working, (in production), as it were, with the int of the decimal
fraction times ten.

i.e your 5.4 => 54 and 5.9 => 59

Should be adaptable from: (not tested)....

condition = ${if >{$sender_rate_limit}{54}{1}{0}}

to: (not tested)...

delay     = ${eval: $sender_rate_int - $sender_rate_limit }s


- may need a multiplier of ten in the limit number used or in the equation..
