Slightly modifying Andreas' answer, it looks like you can pass in the name of the route from urls.py to the template tag. In my example my_tasks, and then in the template tag function use the reverse function to work out what the URL should be, then you can match that against the URL in the request object (available in the template context)

from django import template
from django.core.urlresolvers import reverse

register = template.Library()

@register.tag
def active(parser, token):
    args = token.split_contents()
    template_tag = args[0]
    if len(args) < 2:
        raise template.TemplateSyntaxError, "%r tag requires at least one argument" % template_tag
    return NavSelectedNode(args[1:])

class NavSelectedNode(template.Node):
    def __init__(self, name):
        self.name = name

    def render(self, context):

        if context['request'].path == reverse(self.name[1]):
            return 'active'
        else:
            return ''

urls.py

url(r'^tasks/my', my_tasks, name = 'my_tasks' ),

template.html
