Many of the logic tags have been deprecated in favor of JSTL tags. The
comparison tags fall in this category.
If possible, switch to using JSTL, like so:
<c:if test="${sessionScope.niCount le sessionScope.viewed}">
... some code here ....
</c:if>
<c:if test="${sessionScope.viewed lt sessionScope.niCount}">
... some (hopefully other ;-) code here ....
</c:if>
even better, use <c:choose> since the two conditions are complementary.
If switching is not possible ...

Thats because the "value" attribute is passed the literal "viewed" in
the first case, leading to a String comparison. If you're able to use
EL, pass "${sessionScope.viewed}" instead (if not, a runtime
expression).
