XF 1.5 Add text next to custom user field

So when people register to my site, they have to put in their exam score during registration

I also asked them to put the number of attempt in a different question

I want the number of attempts to appear in parenthesis right next to the exam score on message details


Step 1: 210 (1)

Instead it shows like this:
Step 1: 210
Number of attempts: 1

How can I achieve this?
