As your post recognizes, Asperger's is characterized by social impairment. Repetitive or stereotyped patterns of behavior are also required. In Asperger's, this second category typically involves strong preoccupations with a particular topic or area of interest. Your description did not mention any such preoccupations. The DSM-IV-TR, the manual that guides diagnosis, indicates that many individuals with Asperger's initially receive a diagnosis of ADHD. I think it would be worthwhile to have your son evaluated to be sure that he is receiving the amount and type of support that he needs. Whether or not he receives a diagnosis, it will be important for you and your son's school to work with him on his social issues.
You can ask your GP for a referal to a multi disciplinary team that has experience of diagnosing Aspergers. But for Aspergers he must have had typical language development. You can also google DSM IV for the diagnostic criteria and see if that sounds relevant.
Alot of what you describe is Sensory Integration Disorder. That can be a diagnosis in itself, but also accompanies autistic spectrum disorders including aspergers.
A book that I found very useful was by a woman called Olga Bogdashina called Sensory and Perceptual Differences in Autism and Aspergers. This will explain more about how they perceive sensory information differently. Alot of people recommend Tony Attwood books regarding Aspergers because they are easy to read.
I'm not sure about him being afraid of the neighbours boys. Have they bullied him or teased him in the past? Or he might have been anxious about this unexpected meeting in the streets and tried to avoid it.
