[Dark Byte]

it looks like the value can be bigger than 65535 so try 4 byte big endian.
and turn of fast scan
and make sure mem_mapped is enabled in settings

it's possible it's stored in a way to conserve space or just a made up method to begin with

e.g it the minimum points you get is always dividable by 10 then they might just store a score of 1820 as 182

but easiest might be scanning for your score using a 1 byte value. The value won't show as you've entered but if you freeze it it should be frozen in the game if it's the correct one. from there experiment

and if all else fails, unknown initial value followed by changed/unchanged

[Dark Byte]

no enddianness only affect multiple bytes. a single byte is not affected by this (much)
