Morgan,

The expression (> tx_conta_99 104) in QF_UFIDL does not match the rules:

 "Closed quantifier-free formulas with atoms of the form:
  - p
  - (op (- x y) n),
  - (op (- x y) (- n)),
  - (op x y), or
  where
    - p is a variable or free constant symbol of sort Bool,
    - op is <, <=, >, >=, =, or distinct,
    - x, y are free constant symbols of sort Ints, 
    - n is a numeral. 
 "

though arguably it is the rules that should be changed.
