This does not show any result: (No error but empty output console)
What is "this"? The
int l = soln.getLiteral("score").getInt() ;
Or the whole loop? Maybe there are no solutions and
so you won't see any outputs.
You still have not shown us your data.
We're having to guess what code you are using. You haven't shown
us the result of printing soln.getLiteral("score").
It's very hard to help if you won't answer the questions
we've asked you.
(This is true for more than SPARQL questions.)

However, same query runs when I write:
ResultSetFormatter.out(System.out, results, query);

This is weird. If the query is wrong like you showed here, how can you
get a parse exception?! And as Chris said,
PRINT THE VALUE OF soln.getLiteral("goals") by Java and show us the output.

I know. You said that. But you have ignored my suggestion.
//Goals is already a data property in my owl file and it has
integer value.
How do you know? Show us the data. Show us the code. Show us what
soln.getLiteral("goals") is. Maybe it isn't the integer you think it
is.
OntProperty goals=model.getOntProperty(ns+ "Goals");
How can I get this integer value for future arithmetic
operations.

"goals" contain integer value but it gives me exception:
Error converting typed value to a number.
Print soln.getLiteral("goals") so that we can see the lexical
form and type of the literal. Note that spaces are not
permitted
in integer lexical forms -- make sure there's no extra spaces
in your print.
