Publishing enums with gaps didn't work in 3.2.2, even if they compiled. 
This bug has been fixed.

I can think of these 2 solutions:

1.) Add "unused" enum values to the enum:

TMyEnum = (meOne = 1, meTwo, meThree, meFive = 5);
will become:
TMyEnum = (meUnused1, meOne, meTwo, meThree, meUnused2, meFive);

2.) publish their ordinal value

   property MyEnum: TMyEnum read FMyEnum write FMyEnum;

   property MyEnumOrd: Integer read GetMyEnumOrd write SetEnumOrd; // 
gets/sets MyEnum as ordinal value
