When comparing:
integers, floats: normal mathematical rules apply
EEs, EMs: underlying compare functions for those codes apply
boolean to boolean: FALSE is less than TRUE
string to string: strcmp() rules apply
boolean to anything but a boolean: FALSE is 0, TRUE is 1, and a numeric comparison is used
string to anything but a string: the string is 0, and a numeric comparison is used
| -1 | if *a_ptr < *b_ptr |
| 0 | if *a_ptr == *b_ptr |
| 1 | if *a_ptr > *b_ptr |
pointer to 1st SE_Property_Data_Value to be compared
